scsi: block: Don't check REQ_ATOMIC for reads
[ Upstream commit ea6787c695ab7595d851c3506f67c157f3b593c0 ]
We check in submit_bio_noacct() if flag REQ_ATOMIC is set for both read and
write operations, and then validate the atomic operation if set. Flag
REQ_ATOMIC can only be set for writes, so don't bother checking for reads.
