    Drivers: hv: vmbus: Fix a rescind issue

    The current rescind processing code will not correctly handle
    the case where the host immediately rescinds a channel that has
    been offerred. In this case, we could be blocked in the open call and
    since the channel is rescinded, the host will not respond and we could
    be blocked forever in the vmbus open call.i Fix this problem.
