omxvideodec: retrieve OMX_IndexParamVideoPortFormat before setting it

Browse source 
The usual pattern when setting OMX params is to first get the struct
param, override the values we want to set and then set the updated
param.
We were not doing this with OMX_IndexParamVideoPortFormat and so were
resetting some fields such as OMX_VIDEO_PARAM_PORTFORMATTYPE.xFramerate
