  The single data array data[1] is only used to save the extradata_size.
Replace it with a single element field.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_cmds.h:175:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)

A correct functional change but again please keep the name to `data` not 
`extradata_size`

Then add
