[NETFILTER]: nf_conntrack: optimize __nf_conntrack_find()
Ignoring specific entries in __nf_conntrack_find() is only needed by NAT
for nf_conntrack_tuple_taken(). Remove it from __nf_conntrack_find()
and make nf_conntrack_tuple_taken() search the hash itself.
Saves 54 bytes of text in the hotpath on x86_64:
__nf_conntrack_find | -54 # 321 -> 267, # inlines: 3 -> 2, size inlines: 181 -> 127
nf_conntrack_tuple_taken | +305 # 15 -> 320, lexblocks: 0 -> 3, # inlines: 0 -> 3, size inlines: 0 -> 181
nf_conntrack_find_get | -2 # 90 -> 88
3 functions changed, 305 bytes added, 56 bytes removed, diff: +249
