AVC: Fixed the decode failure of conformance stream MR2_TANDBERG_E.264. (#314)

فهرست منبع 
* * rocDecode/AVC: Fixed the decode failure of conformance stream MR2_TANDBERG_E.264.
 - Fixed a bug in memory management control operation 4 process.

* * rocDecode/AVC: Added the missing assignment of top/bottom POC of ref_pic_list_1 in VAAPI slice parameter struct. This change did not make any effective functional changes.
