media: mtk-vcodec: Remove extra area allocation in an input buffer on encoding 



MediaTek encoder allocates non pixel data area for an input buffer every
plane. As the input buffer should be read-only, the driver should not write
anything in the buffer. Therefore, the extra data should be unnecessary.
