The local nohz kick is currently used by perf which needs it to be
NMI-safe. Recent commit though (7d1311b9)
changed its implementation to fire the local kick using the remote kick
API. It was convenient to make the code more generic but the remote kick
isn't NMI-safe.

As a result:

Lets fix this by restoring the use of local irq work for the nohz local
kick.
