From: Yu Kuai

This patchset fix request uaf in nbd, other drivers might have the
same problem. Will fix them later if this patchset is accepted.
Changes in v2:
- as Bart suggested, add a new helper function for drivers to get
request by tag.
Yu Kuai (2):
blk-mq: add a new interface to get request by tag
nbd: convert to use blk_mq_get_rq_by_tag()
