if: introduce if_first_addr() (and psref variant)

It returns a first address (ifa) of a given family on a given interface.

It will replace a bunch of open codes and make their intent clear.
Apply if_first_addr() and if_first_addr_psref()

in6: introduce in6ifa_first_lladdr() (and psref variant)

It returns a first link-local address (ifa) on a given interface.
Apply in6ifa_first_lladdr() and in6ifa_first_lladdr_psref()
