phonet: Don't hold RTNL for getaddr_dumpit().

getaddr_dumpit() already relies on RCU and does not need RTNL.

Let's use READ_ONCE() for ifindex and register getaddr_dumpit()
with RTNL_FLAG_DUMP_UNLOCKED.

While at it, the retval of getaddr_dumpit() is changed to combine
NLMSG_DONE and save recvmsg() as done in 58a4ff5d77b1 ("phonet: no
longer hold RTNL in route_dumpit()").
