Subject: [PATCH v2 15/18] media: venus: Refactor
 hfi_session_empty_buffer_compressed_pkt

The single element array data[1] is never used. Replace it with a
padding field of the same size.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_cmds.h:146:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
