Subject: [PATCH] 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:

While here, make sure to invoke vxlan_get_rx_port() only when VXLAN
offloads are actually enabled and not when they are only supported.
