Since the uapi does not contain the num_ref_idx_active_override_flag,
drivers for decoders that do not parse slices themselves don't know
how to choose between the num_ref_idx_l[01]_default_active and the
num_ref_idx_l[01]_active override fields.
Instead, userspace must set the override fields to the default values
if the slice does not have the num_ref_idx_active_override flag set.
The drivers will then always enable the override internally and ignore
the default fields completely.
Clarify this requirement in the API documentation.
