vmm: avoid spurious rendezvous 
A vcpu only checks if a rendezvous is in progress or not to decide if it
should handle a rendezvous. This could lead to spurios rendezvous where
a vcpu tries a handle a rendezvous it isn't part of. This situation is
properly handled by vm_handle_rendezvous but it could potentially
degrade the performance. Avoid that by an early check if the vcpu is
part of the rendezvous or not.

At the moment, rendezvous are only used to spin up application
processors and to send ioapic interrupts. Spinning up application
processors is done in the guest boot phase by sending INIT SIPI
sequences to single vcpus. This is known to cause spurious rendezvous
and only occurs in the boot phase. Sending ioapic interrupts is rare
because modern guest will use msi and the rendezvous is always send to
all vcpus.
