Alexander V. Chernikov 3f241e7aac Remove per-packet ifa refcounting from IPv6 fast path. 
Currently ip6_input() calls in6ifa_ifwithaddr() for
 every local packet, in order to check if the target ip
 belongs to the local ifa in proper state and increase
 its counters.

in6ifa_ifwithaddr() references found ifa.
With epoch changes, both `ip6_input()` and all other current callers
 of `in6ifa_ifwithaddr()` do not need this reference
 anymore, as epoch provides stability guarantee.

Given that, update `in6ifa_ifwithaddr()` to allow
 it to return ifa without referencing it, while preserving
 option for getting referenced ifa if so desired.
