[VLAN]: Fix egress priority mappings leak.
These entries are allocated in vlan_dev_set_egress_priority,
but are never released and leaks on vlan device removal.
Drop these in vlan's ->uninit callback - after the device is
brought down and everyone is notified about it is going to
be unregistered.
Found during testing vlan netnsization patchset.
