Cong Zhang be83e65542 blk-mq: Abort suspend when wakeup events are pending ...

[ Upstream commit c196bf43d7 ]

During system suspend, wakeup capable IRQs for block device can be
delayed, which can cause blk_mq_hctx_notify_offline() to hang
indefinitely while waiting for pending request to complete.
Skip the request waiting loop and abort suspend when wakeup events are
pending to prevent the deadlock.

Fixes: bf0beec060 ("blk-mq: drain I/O when all CPUs in a hctx are offline")
