[vproc]: Fix output frame repeated problem

Browse Source 
For IEP2, the first two frames will be deinterlaced at I1O1 mode. I5O2
mode only works when the 3rd frame arrived. Thus the 2nd frame will be
deinterlaced twice and PTS will be repeated as following pattern:
-------------------------------------
IEP in  : 0   1   2       3     4
IEP out : 0   1   0.5 1   2.5 3   3.5
-------------------------------------
To fix this, just skip the 2nd frame processing.
