Deregistration of hid_device_removal_callback fails because the call to
IOHIDDeviceRegisterRemovalCallback doesn't deregister it as it should.
This causes crashes when hid_device_removal_callback is called after
the read_thread has been shutdown.
This patch works around this problem by:
1) Letting the 'dev' hid_device, so that the callback can safely
read the struct, even after the read_thread has been shut down
and the memory should have been freed.
2) Making sure that the two racing callbacks that previously
called CFRunLoopStop, hid_device_removal_callback and
perform_signal_callback, now synchronize and make sure
that CFRunLoopStop is only called once.
