  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)

Oops no.

Please don't change the size of the structure.
