[PATCH net-next] ipvlan: Eliminate duplicated codes with existing function

[gfree . wind]

From: Gao Feng <gfree.w...@vip.163.com>

The recv flow of ipvlan l2 mode performs as same as l3 mode for
non-multicast packet, so use the existing func ipvlan_handle_mode_l3
instead of these duplicated statements in non-multicast case.
