v4l: fwnode: Remove now-redundant loop from v4l2_fwnode_parse_reference()
v4l2_fwnode_parse_reference() relied on counting the number of references for async array memory allocation. The array is long gone so remove counting the references now. This also changes how the function arrives in different unsuccessful return values but the functionality remains unchanged.
