SCSI: sd: Fix handling of NO_SENSE check condition
commit 10dab22664914505dcb804d9ad09cad6bc94d349 upstream
The current handling of NO_SENSE check condition is the same as
RECOVERED_ERROR, and assumes that in both cases, the I/O was fully
transferred.
We have seen cases of arrays returning with NO_SENSE (no error), but
the I/O was not completely transferred, thus residual set. Thus,
rather than return good_bytes as the entire transfer, set good_bytes
to 0, so that the midlayer then applies the residual in calculating
the transfer, and for sd, will fail the I/O and fall into a retry
path.
