inet: introduce inet->inet_flags
Various inet fields are currently racy.
do_ip_setsockopt() and do_ip_getsockopt() are mostly holding
the socket lock, but some (fast) paths do not.
Use a new inet->inet_flags to hold atomic bits in the series.
Remove inet->cmsg_flags, and use instead 9 bits from inet_flags.
