Fix ConnMan crash while disable wifi device

When calling unregister_network() ConnMan sets the network->device pointer
to NULL. That is fine with ESSIDs formed by 1 AP. Otherwise, the eventual
call to __connman_device_decrease_connections() leads to a crash as the
device pointer is NULL.

Fixes BMC #6772
