blk-mq-tag: remove redundant check for 'data->hctx' being non-NULL
We used to pass in NULL for hctx for reserved tags, but we don't do that anymore. Hence the check for whether hctx is NULL or not is now redundant, kill it. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Fixes: a642a158aec6 ("blk-mq-tag: cleanup the normal/reserved tag allocation") Signed-off-by: Jens Axboe <axboe@fb.com>
