At end of spdk_thread_poll(), if thread is in EXITING state, we call thread_exit() to see if the thread can move to EXITED state. If there are any pollers, io_channels or pending device unregistrations in progress, thread_exit() will keep the thread in EXITING mode for this iteration. But a thread may post messages to itself during this cleanup process, so thread_exit() should also check if there are any messages on its queue. Found during testing of spdk_thread lifetime patch set. rbd bdev module will send messages to itself like this during cleanup. Without this change, rbd module testing with bdevperf would cause an spdk_thread to move to EXITED state prematurely.
