Fix x2apic support in bhyve.

When the guest is bringing up the APs in the x2APIC mode a write to the
ICR register will now trigger a return to userspace with an exitcode of
VM_EXITCODE_SPINUP_AP. This gets SMP guests working again with x2APIC.

Change the vlapic timer lock to be a spinlock because the vlapic can be
accessed from within a critical section (vm run loop) when guest is using
x2apic mode.
