#7039: [Network stack] Panic: _mutex_lock (): double lock

Comment (by jackburton):
The problem is that notify_device_monitor acquires the monitor lock (a
mutex), then indirectly calls unregister_device_monitor, which acquires
the lock again.
I changed the mutex_to a recursive_lock, and the problem goes away.
Please someone review the patch.
