Merge branch 'fix-for-bpf_wq-retry-loop-during-free'

Kumar Kartikeya Dwivedi says:

====================
Fix for bpf_wq retry loop during free

Small fix and improvement to ensure cancel_work() can handle the case
where wq callback is running, and doesn't lead to call_rcu_tasks_trace()
repeatedly after failing cancel_work, if wq callback is not pending.
====================
