regulator: twl-regulator: Simplify the code matching regulator id 

This patch makes the code easier to read.

Also add checking the case when no desc id is matched. This is required because
if no desc id is matched, the poiner info is pointed to twl_of_match[i].data
which may be not NULL. Checking info is NULL or not latter does not catch the
error.
