[PATCH 6.10 544/809] Revert "firewire: Annotate struct fw_iso_packet with __counted_by()"

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

commit 00e3913b0416fe69d28745c0a2a340e2f76c219c upstream.

This reverts commit d3155742db89df3b3c96da383c400e6ff4d23c25.

The header_length field is byte unit, thus it can not express the number of
elements in header field. It seems that the argument for counted_by
attribute can have no arithmetic expression, therefore this commit just
reverts the issued commit.
