All callers check the corresponding entry of MpegEncContext.mbintra_table and if set (indicating that the intra tables might have been written to when decodeing a intra MB, so that they are "dirty"), call ff_clean_intra_table_entries(), which resets them to default values and resets the mbintra_table entry. Move resetting to the callers (via an inline function that also performs the checks). This currently has the advantage that the additional load of the mbintra_table ptr can be avoided. It will also allow to simplify ff_clean_intra_table_entries() (by using block_index[4] and [5]).
