[INET]: Uninline the __inet_hash function.
This one is used in quite many places in the networking code and
seems to big to be inline.
After the patch net/ipv4/build-in.o loses ~650 bytes:
add/remove: 2/0 grow/shrink: 0/5 up/down: 461/-1114 (-653)
function old new delta
__inet_hash_nolisten - 282 +282
__inet_hash - 179 +179
tcp_sacktag_write_queue 2255 2254 -1
__inet_lookup_listener 284 274 -10
tcp_v4_syn_recv_sock 755 493 -262
tcp_v4_hash 389 35 -354
inet_hash_connect 1086 599 -487
This version addresses the issue pointed by Eric, that
while being inline this function was optimized by gcc
in respect to the 'listen_possible' argument.
