Jens Axboe 3c782d67c1 blk-mq: fix potential race in queue restart and driver tag allocation ...

Once we mark the queue as needing a restart, re-check if we can
get a driver tag. This fixes a theoretical issue where the needed
IO completes _after_ blk_mq_get_driver_tag() fails, but before we
manage to set the restart bit.
