Both 'bs_dma' and 'dma_addr' are integers. No need to convert the
type from dma_addr_t to uint64_t again.

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.

change the type from unsigned int to dma_addr_t to be able to access
the high bits of the address.

The stateless HEVC decoder saves the instance pointer in the context
regardless if the initialization worked or not. This caused a use after
free, when the pointer is freed in case of a failure in the deinit
function.
Only store the instance pointer when the initialization was successful,
to solve this issue.

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.
