the v4l2-compliance test error below.

In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly
called only when the buffer to free exists, there are some instances
that didn't do the check and triggered warnings in practice.
We believe those checks were forgotten unintentionally. Add the checks
back to fix the warnings.

The VP9 bitstream uses superframes, which each contain 8 sub-frames,
enable accessing the last superframe by increasing the range of the index
vaidation as the maximum number of superframes is 8 and not 7, so that the
last sub-frame can be decoded normally with the stateful VP9 decoder.
