Once we enable -Wall for BPF sources, compiler will complain about lots
of unused variables, variables that are set but never read, etc.
Fix all these issues first before enabling -Wall in Makefile.

Those hooks run as BPF_CGROUP_RUN_SA_PROG_LOCK and operate on a locked socket.
Note that we could remove the switch for prog->expected_attach_type altogether
since all current sock_addr attach types are covered. However, it makes sense
to keep it as a safe-guard in case new sock_addr attach types are added that
might not operate on a locked socket. Therefore, avoid to let this slip through.

I'll extend them in the next patch. It's easier to work with C
than with asm.
