[SCSI] ibmvfc: Fix double completion on abort timeout

If an abort request times out to the virtual fibre channel adapter,
the ibmvfc driver will kick off a reset of the adapter. This
patch ensures we wait for the both the abort request and the
request being aborted to be completed prior to exiting the
eh_abort handler. This fixes a bug where the ibmvfc driver
was erroneously returning success to the eh_abort handler
then later sending back a response to the same command.

The device limit of 128 tape drives was established in 2003 as a
significant increase from the 8 tape drives allowed previously.

We're seeing customer sites that between a large number of drives
and multipath are discovering more than 128 devices and running
into problems.

Now that we're not stuck having to store a pointer in array
and aren't limited by kmalloc failing on higher order allocs we can
lift the limit to fill the entire minor range based on the number
of modes.

Based on the current code, that's 2^17 devices.
