Merge branch 'inet-better-inet_sock_set_state-for-passive-flows'

Eric Dumazet says:

====================
inet: better inet_sock_set_state() for passive flows

Small series to make inet_sock_set_state() more interesting for
LISTEN -> TCP_SYN_RECV changes : The 4-tuple parts are now correct.

First patch is a cleanup.
