selftests/mm: fix "warning: expression which evaluates to zero..." in mlock2-tests.c

The stop variable is a char*, and the code was assigning a char value to
it. This was generating a warning when compiling with clang.

However, as both David and Peter pointed out, stop is not even used
after the problematic assignment to a char type. So just delete that
line entirely.
