scsi: qla2xxx: Really fix qla2xxx_eh_abort()
I'm not sure how this happened but the patch that was intended to fix abort
handling was incomplete. This patch fixes that patch as follows:
- If aborting the SCSI command failed, wait until the SCSI command
completes.
- Return SUCCESS instead of FAILED if an abort attempt races with SCSI
command completion.
- Since qla2xxx_eh_abort() increments the sp reference count by calling
sp_get(), decrement the sp reference count before returning.
