By passing as length of the MAC addresses -1 for both arguments, one
could get through to compare empty strings, NULL, and addresses longer
than the maximum. Such addresses are not valid, and they should never
compare equal (not even to themselves).
This is a change in behavior of public API, but it never made sense to
claim two addresses are equal, when they are not even valid addresses.
Also, avoid undefined behavior with "NULL, -1, NULL, -1" arguments,
where we would call memcmp() with zero length and NULL arguments.
UBSan flags that too.
