net: vlan: suppress "failed to kill vid" warnings
When a real dev unregisters, vlan_device_event() also unregisters all of its vlan interfaces. For each VID this ends up in __vlan_vid_del(), which attempts to remove the VID from the real dev's VLAN filter. But the unregistering real dev might no longer be able to issue the required IOs, and return an error. Subsequently we raise a noisy warning msg that is not appropriate for this situation: the real dev is being torn down anyway, there shouldn't be any worry about cleanly releasing all of its HW-internal resources. So to avoid scaring innocent users, suppress this warning when the failed deletion happens on an unregistering device. While at it also convert the raw pr_warn() to a more fitting netdev_warn().
