scsi: block: Don't check REQ_ATOMIC for reads

Browse Source 
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.

Fixes: 9da3d1e912 ("block: Add core atomic write support")
