[SCSI] qla4xxx: add iscsi_transport capps for fw capacilities

Userspace will want to know what the driver/FW/HW capabilites
when it comes to some operations like if the hardware can
do discovery or if it can store iscsi info like what target
was used for boot. This patch adds some new caps so userspace
can tell if the driver supports hardware/fw based sendtargets
discovery and if the hardware has some flash which may be
holding or can contain some iscsi target info
.
