Julian Wiedmann bd706ff8ea 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().
