x25: decrement netdev reference counts on unload
commit 171995e5d82dcc92bea37a7d2a2ecc21068a0f19 upstream.
x25 does not decrement the network device reference counts on module unload.
Thus unregistering any pre-existing interface after unloading the x25 module
hangs and results in
unregister_netdevice: waiting for tap0 to become free. Usage count = 1
This patch decrements the reference counts of all interfaces in x25_link_free,
the way it is already done in x25_link_device_down for NETDEV_DOWN events.
