Vlad Buslov ace0ab3a4b Revert "vlan: Fix VLAN 0 memory leak"
This reverts commit 718cb09aaa.

The commit triggers multiple syzbot issues, probably due to possibility of
manually creating VLAN 0 on netdevice which will cause the code to delete
it since it can't distinguish such VLAN from implicit VLAN 0 automatically
created for devices with NETIF_F_HW_VLAN_CTAG_FILTER feature.
