net: atm: clean up a range check
The code works fine but the problem is that check for negatives is a
no-op:
if (arg < 0)
i = 0;
The "i" value isn't used. We immediately overwrite it with:
i = array_index_nospec(arg, MAX_LEC_ITF);
The array_index_nospec() macro returns zero if "arg" is out of bounds so
this works, but the dead code is confusing and it doesn't look very
intentional.
