netfilter: nft_masq: correct length for loading protocol registers

[ Upstream commit ec2c5917eb858428b2083d1c74f445aabbe8316b ]

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.
