David Matlack d08dd068ad jump_labels: API for flushing deferred jump label updates
commit b6416e6101 upstream.

Modules that use static_key_deferred need a way to synchronize with
any delayed work that is still pending when the module is unloaded.
Introduce static_key_deferred_flush() which flushes any pending
jump label updates.
