inet: add READ_ONCE(sk->sk_bound_dev_if) in INET_MATCH()

inet: add READ_ONCE(sk->sk_bound_dev_if) in INET_MATCH()

[ Upstream commit 4915d50e300e96929d2462041d6f6c6f061167fd ]

INET_MATCH() runs without holding a lock on the socket.

We probably need to annotate most reads.

This patch makes INET_MATCH() an inline function
to ease our changes.

v2:

We remove the 32bit version of it, as modern compilers
should generate the same code really, no need to
try to be smarter.

Also make 'struct net *net' the first argument.
