bridge: vlan: fix usage of vlan 0 and 4095 again
Vlan ids 0 and 4095 were disallowed by commit:
1945addea6d8 ("bridge: Don't use VID 0 and 4095 in vlan filtering")
but then the check was removed when vlan ranges were introduced by:
57540eed2da2 ("bridge: support for multiple vlans and vlan ranges in setlink and dellink requests")
So reintroduce the vlan range check.
Before patch:
[root@testvm ~]# bridge vlan add vid 0 dev eth0 master
(succeeds)
After Patch:
[root@testvm ~]# bridge vlan add vid 0 dev eth0 master
