Usually automatically forwarded UDP outbound ports are set up by
udp_port_rebind_outbound() called from udp_timer(). However, the very
first time they're created and bound is by udp_sock_init_ns() called from
udp_init(). udp_sock_init_ns() is essentially an unnecessary cut down
version of udp_port_rebind_outbound(), so we can jusat remove it.
Doing so does require moving udp_init() below udp_port_rebind_outbound()'s
definition.
