CVE-2026-98285

net: bridge: vlan: fix bugs caused by switchdev deletion errors

In the Linux kernel, the following vulnerability has been resolved:

net: bridge: vlan: fix bugs caused by switchdev deletion errors

Allowing switchdev to prevent vlan deletion and error out in __vlan_del
could cause multiple different issues - inconsistent state, memory leaks
when flushing, NULL pointer dereference on bridge error when flushing.
It doesn't make sense to allow it to stop __vlan_del, so log the error
and continue with software vlan deletion. This is also consistent with
8021q behaviour.
