The cached request lookups reject a request whose op_is_flush() state does
not match the incoming operation. That check is from when rq->elv and
rq->flush shared a union, so a request could not be both a scheduler
request and carry flush state. Commit be4c427809 ("blk-mq: use the I/O
scheduler for writes from the flush state machine") made them separate
members of struct request.
A cached request now gets its scheduler state when it is claimed by an
operation, so one claimed for a flush is set up exactly as a freshly
allocated request. Drop the check so a cached batch can mix flush and
non-flush operations.
