media: rc-main: clean-up two warnings 

While correct, the code is too complex for smatch to undersdand
that protocol will always be initialized:

	drivers/media/rc/rc-main.c:1531 store_wakeup_protocols() error: uninitialized symbol 'protocol'.
	drivers/media/rc/rc-main.c:1541 store_wakeup_protocols() error: uninitialized symbol 'protocol'.

So, change it a little bit in order to avoid such warning.
