sgi-xp: incoming XPC channel messages can come in after the channel's partition structures have been torn down
Under some workloads, some channel messages have been observed being delayed on the sending side past the point where the receiving side has been able to tear down its partition structures. This condition is already detected in xpc_handle_activate_IRQ_uv(), but that information is not given to xpc_handle_activate_mq_msg_uv(). As a result, xpc_handle_activate_mq_msg_uv() assumes the structures still exist and references them, causing a NULL-pointer deref.
