media: rc: ensure close() is called on rc_unregister_device



[ Upstream commit 8e782fcf78275f505194e767c515202d4fd274bc ]

If userspace has an open file descriptor on the rc input device or lirc
device when rc_unregister_device() is called, then the rc close() is
never called.

This ensures that the receiver is turned off on the nuvoton-cir driver
during shutdown.
