cbs_h264, h264_metadata: Deleting SEI messages never fails
Given the recent changes to ff_cbs_delete_unit, it is no longer sensible
to use a return value for ff_cbs_h264_delete_sei_message; instead, use
asserts to ensure that the required conditions are met and remove the
callers' checks for the return value. Also, document said conditions.
An assert that is essentially equivalent to the one used in
ff_cbs_delete_unit has been removed, too.
