Jeffy Chen ffb7640acb Bluetooth: cmtp: fix possible might sleep error in cmtp_session 
commit f06d977309d09253c744e54e75c5295ecc52b7b4 upstream.

It looks like cmtp_session has same pattern as the issue reported in
old rfcomm:

	while (1) {
		set_current_state(TASK_INTERRUPTIBLE);
		if (condition)
			break;
		// may call might_sleep here
		schedule();
	}
	__set_current_state(TASK_RUNNING);

Which fixed at:
	dfb2fae Bluetooth: Fix nested sleeps

So let's fix it at the same way, also follow the suggestion of:
