net: fix sparse endianness warnings on sock_common
# make C=2 CF=-D__CHECK_ENDIAN__ net/ipv4/inet_hashtables.o ... net/ipv4/inet_hashtables.c:242:7: warning: restricted __portpair degrades to integer net/ipv4/inet_hashtables.c:242:7: warning: restricted __addrpair degrades to integer ... Move __portpair/__addrpair from include/net/inet_hashtables.h to include/net/sock.h where we need them in struct sock_common Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Ling Ma <ling.ma.program@gmail.com> Signed-off-by: David S.
