net: bridge: vlan: fix error return code in __vlan_add()
[ Upstream commit ee4f52a8de2c6f78b01f10b4c330867d88c1653a ]
Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.
Fixes: f8ed289fab84 ("bridge: vlan: use br_vlan_(get|put)_master to deal with refcounts")
