msdk: specify the way to find a proper cached response by request

Browse source 
The current way to find proper response by just comparing request's
value is wrong.  We need to compare the size of a frame and the
number of suggested frames.

Refer to the sample in https://github.com/Intel-Media-SDK/samples.
