Ming Lei d937647284 block: make sure local irq is disabled when calling __blkcg_rstat_flush 
commit 9c39b7a905 upstream.

When __blkcg_rstat_flush() is called from cgroup_rstat_flush*() code
path, interrupt is always disabled.

When we start to flush blkcg per-cpu stats list in __blkg_release()
for avoiding to leak blkcg_gq's reference in commit 20cb1c2fb7
("blk-cgroup: Flush stats before releasing blkcg_gq"), local irq
isn't disabled yet, then lockdep warning may be triggered because
the dependent cgroup locks may be acquired from irq(soft irq) handler.

Fix the issue by disabling local irq always.

Fixes: 20cb1c2fb7 ("blk-cgroup: Flush stats before releasing blkcg_gq")
