netifd: Fix multiple -Wsign-compare warnings
This fixes warnings like this:
warning: comparison of integer expressions of different signedness: 'int' and 'long unsigned int' [-Wsign-compare]
Mostly this was an int compared to a size_t returned by ARRAY_SIZE().
The easiest fix is to count on the size_t type.
The ifindex is sometimes an unsigned int and sometimes a signed int in
the kernel interfaces. I think it normally fits into an unsigned 16 bit
value, so this should be fine. Do the one comparison where the
compiler complains as a long.
Casting the result of sizeof() to int should be safe. These values are
never out of range of int.
