Mark Johnston b265a2e0d7 vmm: Fix AP startup compatibility for old bhyve executables 
These changes unbreak AP startup when using a 13.1-RELEASE bhyve
executable with a newer kernel:
- Correct the destination mask for the VM_EXITCODE_IPI message generated
  by an INIT or STARTUP IPI in vlapic_icrlo_write_handler().
- Only initialize vlapics on active vCPUs.  13.1-RELEASE bhyve activates
  AP vCPUs only after the BSP starts them with an IPI, and vmm now
  allocates vcpu structures lazily, so the STARTUP handling in
  vm_handle_ipi() could trigger a page fault.
- Fix an off-by-one setting the vcpuid in a VM_EXITCODE_SPINUP_AP
  message.
