[IPV4]: Uninline netfilter okfns
Now that we don't pass double skb pointers to nf_hook_slow anymore, gcc
can generate tail calls for some of the netfilter hook okfn invocations,
so there is no need to inline the functions anymore. This caused huge
code bloat since we ended up with one inlined version and one out-of-line
version since we pass the address to nf_hook_slow.
Before:
text data bss dec hex filename
8997385 1016524 524652 10538561 a0ce41 vmlinux
After:
text data bss dec hex filename
8994009 1016524 524652 10535185 a0c111 vmlinux
-------------------------------------------------------
-3376
All cases have been verified to generate tail-calls with and without
netfilter. The okfns in ipmr and xfrm4_input still remain inline because
gcc can't generate tail-calls for them.
