kernel - Change IPI recovery watchdog

* Change the default recovery watchdog timeout for IPIs from 1/16 second
  to 2 seconds and the repeated timeout from 1/2 second to 2 seconds.

* Add missing initialization to pmap_inval_smp_cmpset(), without it an
  improper watchdog timeout/retry could occur.

* This still may not fix issues with VMs when core threads cause extreme
  latencies on the host.
