[PATCH 3/7] name_equal: return early from function if src null-terminates in the loop

[Marin Ramesa]

Return early from function if src null-terminates in the loop before
the target does. This is to prevent pointers going to addresses beyond
null-termination.

* device/dev_name.c (name_equal): Check if src null-terminates in the loop.
