Avoid undefined pointer arithmetic while growing mmap
The undefined behaviour sanitizer complains with:
runtime error: addition of unsigned offset to 0x… overflowed to 0x…
Compilers and runtime do the right thing in any case and it is a
codepath that can (and ideally should) be avoided for speed reasons
alone, but fixing it can't hurt (too much).
