lib/cmdline.c: fix get_options() overflow while parsing ranges
commit a91e0f680bcd9e10c253ae8b62462a38bd48f09f upstream.
When using get_options() it's possible to specify a range of numbers,
like 1-100500. The problem is that it doesn't track array size while
calling internally to get_range() which iterates over the range and
fills the memory with numbers.
