    glusterd: ignore RPC events when glusterd is shutting down

    When glusterd receives a SIGTERM while it receives RPC
    connect/disconnect/destroy events, the thread might lead to a crash
    while accessing rcu_read_lock () as the clean up thread might have
    already freed up the resources. This is more observable when glusterd
    comes up with upgrade mode = on during upgrade process.

    The solution is to ignore these events if glusterd is already in the
    middle of cleanup_and_exit ().
