Subject: [PATCH 1/2] media: venus: hfi_cmds: struct hfi_session_release_buffer_pkt: Replace 1-element array with flexible array

Replace the deprecated[1] use of a 1-element array in
struct hfi_session_release_buffer_pkt with a modern flexible array.

No binary differences are present after this conversion.
