[SCSI] switch sdev sysfs attributes to default attributes
This removes the unused sysfs attribute overwriting logic for most of

creation.
Without this patch, at the time of the events for the SCSI LUN's, there
will be no sysfs files, because their creation is delayed until the sd

[SCSI] mpt fusion: Add support for ATTO 4LD: Rebranded LSI
53C1030
Per request from Matthew Wilcox - using PCI_VENDOR_ATTO.
Add support for ATTO UL4D, they are rebranded
53C1030.
The changes are
1. Adding a new PCI vendor ID in pci table
2. The spi_port_page_2 is in different format than that of LSI generic
spi_port_page_2 and hence mapping code is added.

[SCSI] lpfc: fix potential overflow of hbqs array
The Coverity checker noticed that we may overrun a statically allocated
array in drivers/scsi/lpfc/lpfc_sli.c::lpfc_sli_hbqbuf_find().
The case is this; In 'struct lpfc_hba' we have
#define LPFC_MAX_HBQS 4
...
struct lpfc_hba {
...
struct hbq_s hbqs[LPFC_MAX_HBQS];
...
};
But then in lpfc_sli_hbqbuf_find() we have this code
hbqno = tag >> 16;
if (hbqno > LPFC_MAX_HBQS)
return NULL;
if 'hbqno' ends up as exactely 4, then we won't return, and then this
list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) {
will cause an overflow of the statically allocated array at index 4,
since the valid indices are only 0-3.
I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS'
into 'hbqno >= LPFC_MAX_HBQS' as a possible fix.

[SCSI] Fix async scanning double-add problems
Stress-testing and some thought has revealed some places where
asynchronous scanning needs some more attention to locking.
- Since async_scan is a bit, we need to hold the host_lock while
modifying it to prevent races against other CPUs modifying the word
that bit is in. This is probably a theoretical race for the moment,
but other patches may change that.
- The async_scan bit means not only that this host is being scanned
asynchronously, but that all the devices attached to this host are not
yet added to sysfs. So we must ensure that this bit is always in sync.
I've chosen to do this with the scan_mutex since it's already acquired
in most of the right places.
- If the host changes state to deleted while we're in the middle of
a scan, we'll end up with some devices on the host's list which must
be deleted. Add a check to scsi_sysfs_add_devices() to ensure the
host is still running.
- To avoid the async_scan bit being protected by three locks, the
async_scan_lock now only protects the scanning_list.

[SCSI] add srp transport class
This adds srp transport class that works with ib_srp and ibmvscsi.
It creates only /sys/class/{srp_host,srp_remote_ports} and
srp_remote_ports has only "port_id" attribute.
