Fix issue where the worker functions for handling G2H messages for
pagefaults and access counters are not run even though we have pending
fault to service.

v2:
Matt Brost asked me to resend this version 2 which requeues the worker as
alternative compared to the v1 [1]. However, this will add latency if
servicing many faults and encounter context switch when requeuing the
worker. Perhaps start here and tune this later. I put TODO comments in
the worker functions for now.
