6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yang Xiuwei <redacted>
[ Upstream commit a640d4546b11be5709a82bdc63d7dafd8ddc6c9e ]
Only enter the sense_key switch when the command returned CHECK
CONDITION with valid, non-deferred sense. The old condition let deferred
or invalid sense fall through and mis-handle the I/O.
Fixes: 03aba2f79594 ("[SCSI] sd/scsi_lib simplify sd_rw_intr and scsi_io_completion")
