CHROMIUM: [media] rockchip-vpu: Fix inactive reference frame configuration

If we assign 0 to the inactive DPB position in RPS packet,
HW will treat that as a true reference frame with pic_num 0
when frame pic_num 0 is in the reference list and cause
output picture corruption.

To fix it, this patch changes the code to assign an invalid
pic_num to RPS packet to prevent HW from referring to an
invalid reference frame.
