Replace the old style single element array at the end of the struct with
a flex array.

The code does not allocate this structure, so the size change should not
be a problem.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_helper.h:1233:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
