[ 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.
