[h264d]: Fix dpb stuck issue on decoding airplay

Browse Source 
The no_output_of_prior_pics_flag flag in apple airplay stream is true.
This will cause dpb slot leak in idr_memory_management function.
The no_output_of_prior_pics_flag flag require the frame before IDR frame
should be discard rather than display. So we need to unmark the frames
in dpb and then mark them to be displayed to avoid they to be send to
display queue.

NOTE: when clearing no output frame we need to remove it first with
p_mark->out_flag is false to insure the CODEC_USE flag in mpp_buf_slot is
clear. Then set is_output flag to true to avoid real output this frame
to display queue.
