Mark Johnston 4c812fe61b vlapic: Schedule callouts on the local CPU 
The virtual LAPIC driver uses callouts to implement the LAPIC timer.
Callouts are armed using callout_reset_sbt(), which currently puts
everything on CPU 0.  On systems running many bhyve VMs this results in
a large amount of contention for CPU 0's callout lock.

Modify vlapic to schedule callouts on the local CPU instead.  This
allows timer interrupts to be scheduled more evenly among CPUs where
bhyve is running.
