inet: set/get simple options locklessly
Now we have inet->inet_flags, we can set following options
without having to hold the socket lock:
IP_PKTINFO, IP_RECVTTL, IP_RECVTOS, IP_RECVOPTS, IP_RETOPTS,
IP_PASSSEC, IP_RECVORIGDSTADDR, IP_RECVFRAGSIZE.
ip_sock_set_pktinfo() no longer hold the socket lock.
Similarly we can get the following options whithout holding
the socket lock:
IP_PKTINFO, IP_RECVTTL, IP_RECVTOS, IP_RECVOPTS, IP_RETOPTS,
IP_PASSSEC, IP_RECVORIGDSTADDR, IP_CHECKSUM, IP_RECVFRAGSIZE.
