[media] rc: sunxi-cir: Initialize the spinlock properly

Browse Source 
The driver allocates the spinlock but fails to initialize it correctly.
The kernel reports a BUG indicating bad spinlock magic when spinlock
debugging is enabled.

Call spin_lock_init() on it to initialize it correctly.

Fixes: b4e3e59fb5 ("[media] rc: add sunxi-ir driver")
