net: use indirect call helpers for sk->sk_prot->release_cb()

Browse source

When adding sk->sk_prot->release_cb() call from __sk_flush_backlog()
Paolo suggested using indirect call helpers to take care of
CONFIG_RETPOLINE=y case.

It turns out Google had such mitigation for years in release_sock(),
it is time to make this public :)
