Subject: [PATCH V2 5/5 net-next] vxlan: fix vxlan_find_sock() documentation for l3mdev

Since commit aab8cc3630e32
("vxlan: add support for underlay in non-default VRF")

vxlan_find_sock() also checks if socket is assigned to the right
level 3 master device when lower device is not in the default VRF.
