[media] lbdt3306a: simplify the lock status check
The logic there is too complex and it looks like an inifite
loop.
So, simplify the logic and implement it as a for loop.
This gets rid of the following checkpatch.pl warnings:
WARNING: else is not generally useful after a break or return
+ return LG3306_UNLOCK;
+ } else {
WARNING: else is not generally useful after a break or return
+ return LG3306_UNLOCK;
+ } else {
