V4L/DVB (13540): ir-common: Cleanup get key evdev code
The same loop to seek for a key were used on different places. Also,
no spinlock were protecting it to avoid the risk of replacing a keycode
while seeking for a new code.
This cleanup does:
- create an unique function to seek for a code;
- adds an spinlock to protect the table lookup;
- remove some unused code;
- simplifies to code to make it easier to understand.
Basically no change in behavior should be noticed after this patch.
