vxlan: Accept user specified MTU value when create new vxlan link
[ Upstream commit ce577668a426c6a9e2470a09dcd07fbd6e45272a ]
When create a new vxlan link, example:
ip link add vtap mtu 1440 type vxlan vni 1 dev eth0
The argument "mtu" has no effect, because it is not set to conf->mtu. The
default value is used in vxlan_dev_configure function.
This problem was introduced by commit 0dfbdf4102b9 (vxlan: Factor out device
configuration).
