netfilter: nf_tables: nft_parse_register can return a negative value 



Since commit 6e1acfa3 ("netfilter: nf_tables: validate registers
coming from userspace.") nft_parse_register can return a negative value,
but the function prototype is still returning an unsigned int.

Fixes: 6e1acfa3 ("netfilter: nf_tables: validate registers coming from userspace.")
