vlan: Fix register_vlan_dev() error path
[ Upstream commit 6b863d1d3239eff0f45c2e6e672f5b56db828db0 ]
In case register_netdevice() returns an error, and a new vlan_group
was allocated and inserted in vlan_group_hash[] we call
vlan_group_free() without deleting group from hash table. Future
lookups can give infinite loops or crashes.
We must delete the vlan_group using RCU safe procedure.
