Remove unintended filter form from child object tabs

The filter form block added to object_children.html caused a collapsible
filter panel to appear on all child object tabs (Console Ports, Power
Ports, Interfaces, etc.) for views that have filterset_form set — a much
broader change than intended. Remove the block entirely.

Also remove filterset_form from DeviceInterfacesView since the
InterfaceFilterForm is a global form with device/location-level fields
inappropriate for the device-specific interface tab; the filterset alone
is sufficient for URL-param filtering.
