manager: fix race condition when resuming from sleep

Browse source 
If the device state change (to disconnected or unmanaged) triggered by
a sleep event happens after the wake, the devices becomes wrongly
unmanaged and it's necessary to manually manage it again, or restart
NM.

During the wake event we should disconnect the device_sleep_cb()
callback for all devices because we don't want to react to state
changes anymore; in particular we don't need to detect when the device
becomes disconnected to unmanage it.
