net: add add indirect call wrapper in skb_release_head_state()
While stress testing UDP senders on a host with expensive indirect
calls, I found cpus processing TX completions where showing
a very high cost (20%) in sock_wfree() due to
CONFIG_MITIGATION_RETPOLINE=y.
Take care of TCP and UDP TX destructors and use INDIRECT_CALL_3() macro.
