[v6,01/10] media: venus: Use flex array for hfi_session_release_buffer_pkt

Commit Message

Replace the old style single element array with a flex array. We do not
allocate this structure, so the size change should not be an issue.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_cmds.h:204:5-16: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)

Could you inverse the order of the tags, please. "Signed-off-by" must be
first and then the others.

All patches in the series has this issue.

Just sent a v7 taking care of this.

I am almost sure that I used b4 to import the tags.... Are we sure
that this is a policy that we should follow?
