mm-video: vidc: Allow client to change input buffer size

When IL client has modified OMX_PortDefType.nBufferSize on the input
port, use the client specified size.  For decoding session, the client
is more likely to know about the max buffer size, rather than the
component or the driver, which just guesses the max buffer size.
