monitor-utils: clear cam data after creating nodes

Browse source 
The cam_data structure stores a reference to the "parent" WpSpaDevice
and doesn't allow it to be destroyed when the monitor detects that
the device is no longer present. Clear it right after pushing the event
to make sure there's no dangling reference left around

Fixes: #627
