net/mlx4_en: Add VXLAN ndo calls to the PF net device ops too
This is currently missing, which results in a crash when one attempts
to set VXLAN tunnel over the mlx4_en when acting as PF.
[ 2408.785472] BUG: unable to handle kernel NULL pointer dereference at (null)
[...]
[ 2408.994104] Call Trace:
[ 2408.996584] [<ffffffffa021f7f5>] ? vxlan_get_rx_port+0xd6/0x103 [vxlan]
[ 2409.003316] [<ffffffffa021f71f>] ? vxlan_lowerdev_event+0xf2/0xf2 [vxlan]

[ 2409.017132] [<ffffffffa063070f>] mlx4_en_open+0x17f/0x1b8 [mlx4_en]
While here, make sure to invoke vxlan_get_rx_port() only when VXLAN
offloads are actually enabled and not when they are only supported.
