    vmm: remove unneccessary rendezvous assertion
    
    When a vcpu sees that a rendezvous is in progress, it exits and tries to
    handle the rendezvous. The vcpu doesn't check if it's part of the
    rendezvous or not. If the vcpu isn't part of the rendezvous, the
    rendezvous could be done before it reaches the assertion. This will
    cause a panic.
    
    The assertion isn't needed at all because vm_handle_rendezvous properly
    handles a spurious rendezvous. So, we can just remove it.
