    hyperv/evttimer: Use an independent message slot so that it can work

    Using the same message slot as the other types of the messages has
    the side effect that the event timer message could be deferred to
    the swi threads to run (lacking of trapframe and the original code
    didn't even handle that, so the event timer was actually broken).

    As of this commit we use an independent message slot for event timer,
    so that we could handle all of event timer messages in the interrupt
    handler directly.  Note, the message slot for event timer is still
    bind to the same interrupt vector as the other types of messages.

    hyperv/vmbus: Create per-cpu fast taskqueue for msg handling

    Using one taskqueue does not work, since the EOM MSR must be written
    on the msg's owner CPU.
