media: mediatek: vcodec: Only free buffer VA that is not NULL

Browse Source 
[ Upstream commit eb005c801e ]

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.
