netfilter: nft_range: validate operation netlink attribute

Use nft_parse_u32_check() to make sure we don't get a value over the
unsigned 8-bit integer. Moreover, make sure this value doesn't go over
the two supported range comparison modes.

Fixes: 9286c2eb1fda ("netfilter: nft_range: validate operation netlink attribute")
