Subject: blk-mq: remove non-blocking pass in blk_mq_map_request

bt_get already does a non-blocking pass as well as running the queue
when scheduling internally, no need to duplicate it.

Looks good too,

Reviewed-by: Sagi Grimberg <sagi@xxxxxxxxxxx>

Question (while we're on the subject):
Do consumers have a way to restrict blk-mq to block on
lack of tags? I'm thinking in the context of nvme-target
that can do more useful things than waiting for a tag...
