objects: update the old location parent_addr only if it has value

Browse Source 
Do not update extra_update['phys_function'] in case parent_addr
field is None. Updating it leads to an exception as extra_update
is a dictionary of non-nullable fields.

Partially implements blueprint sriov-physical-function-passthrough
