mm-video: vdec: update extra data buffer count in setparmater

If the extra data buffer count is not updated, then
the extra buffer allocation happens with the old buffer
count. This buffer falls short to contain extra data
information for all o/p buffers and we see an out of
bounds access during handle_extra data for the additional
o/p buffers.
