target: Fix zero-length MODE_SENSE regression
This patch fixes a regression introduced in v3.8-rc1 code where
a zero-length MODE_SENSE was no longer returning GOOD status, but
instead returning TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE to generate
a CHECK_CONDITION status.
This regression was introduced with the following commit:
commit de103c93aff0bed0ae984274e5dc8b95899badab
Author: Christoph Hellwig <hch@lst.de>
Date: Tue Nov 6 12:24:09 2012 -0800
target: pass sense_reason as a return value
and this patch has been tested with the following zero-length CDB:
sg_raw /dev/sdd 5a 00 0a 00 00 00 00 00 00 00
SCSI Status: Good
Sense Information:
sense buffer empty
