phonet: Convert phonet_routes.lock to spinlock_t.
route_doit() calls phonet_route_add() or phonet_route_del()
for RTM_NEWROUTE or RTM_DELROUTE, respectively.
Both functions only touch phonet_pernet(dev_net(dev))->routes,
which is currently protected by RTNL and its dedicated mutex,
phonet_routes.lock.
We will convert route_doit() to RCU and cannot use mutex inside RCU.
Let's convert the mutex to spinlock_t.
