vmh264: fix frame mode playback not smooth issue [1/1]

Browse Source 
PD#SWPL-5926

Problem:
In frame mode and frmbase_cont_bitlevel > 0 case. with some stream
driver will finish search start code until H264_SEARCH_BUFEMPTY. it
will cost 2+ vsync time. decoder will be blocked. actually, in frame mode
decoder don't need to wait for timeout. decoder should return with
H264_SEARCH_BUFEMPTY once bitlevel is very low.

Solution:
skip search start code vsync timeout wait in frame mode
