Log Message:
Revert the changes made in the commit:

  "Do not queue functions via sysmon_taskq(9) in the pmf(9) resume hooks.
   There is a small and unlikely race when the drivers are loaded as modules;
   suspend, resume, queue a function, and immediately unload the module."

Queueing the checks in the resume hooks was observed to improve the resume
time by several seconds (!) on a system with poorly implemented AML code.
The observed race condition is a wider issue related to modules; things like
sysmon_taskq(9) should be modified to allow cancelling of queued functions.
