[IPV4]: INET_MATCH() annotations
INET_MATCH() and friends depend on an interesting set of kludges:
* there's a pair of adjacent fields in struct inet_sock - __be16 dport
followed by __u16 num. We want to search by pair, so we combine the keys into
a single 32bit value and compare with 32bit value read from &...->dport.
* on 64bit targets we combine comparisons with pair of adjacent __be32
fields in the same way.
Make sure that we don't mix those values with anything else and that pairs
we form them from have correct types.
