netfilter: nft_redir: correct length for loading protocol registers
The values in the protocol registers are two bytes wide. However, when
parsing the register loads, the code currently uses the larger 16-byte
size of a `union nf_inet_addr`. Change it to use the (correct) size of
a `union nf_conntrack_man_proto` instead.
