    swscale/ops: always call ff_sws_op_list_update_comps() before printing

    This tightens a pre-existing quirk, which is that ff_sws_op_list_print()
    already trusts the metadata being accurate going into the call, though we
    allowed the absence of metadata as an explicitly tolerated special case.

    With this wording change, we now require that the metadata is always
    up-to-date, which resolves a few annoying discrepancies that would otherwise
    show up as a result of the following refactors.
