smp: don't warn about csd->flags having CSD_FLAG_LOCK cleared for !wait
blk-mq reuses the request potentially immediately, since the most cache hot is always given out first. This means that rq->csd could be reused between csd->func() being called and csd_unlock() being called. This isn't a problem, since we never use wait == 1 for the smp call function. Add CSD_FLAG_WAIT to be able to tell the difference, retaining the warning for other cases. Cc: Ingo Molnar <mingo@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
