[PATCH 2/2] media: venus: hfi_cmds: struct hfi_session_release_buffer_pkt: Add __counted_by annotation

[Kees Cook <kees@kernel.org>]

The only direct user of struct hfi_session_release_buffer_pkt is
pkt_session_unset_buffers() which sets "num_buffers" before using it
as a loop counter for accessing "buffer_info". Add the __counted_by
annotation to reflect the relationship.
