avcodec/cbs_mpeg2: Remove redundant counter
Use -1 as the position in ff_cbs_insert_unit_data() which implicitly reuses frag->nb_units as the counter. Also switch to a do-while-loop, as it is more natural than a for-loop now that the counter is gone. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
