xfrm_state4.c and state6.c are both part of ipv4/ipv6 (depends on
CONFIG_XFRM, a boolean) but even if ipv6 is a module state6.c can't
be removed (ipv6 lacks module_exit so it cannot be removed).

The only callers for xfrm6_fini that leads to state backend unregister
are error unwinding paths that can be called during ipv6 init function.

So after ipv6 module is loaded successfully the state backend cannot go
away anymore.

The family value from policy lookup path is taken from dst_entry, so
that should always be AF_INET(6).

However, since this silences the warning and avoids readers of this
code wondering about possible null deref it seems preferrable to
be defensive and just add the old check back.
