Subject: [PATCH] task_work: add kerneldoc annotation for 'data' argument

A previous commit changed the arguments to task_work_cancel_match(),
but didn't document all of them.

Fixes: c7aab1a7c52b ("task_work: add helper for more targeted task_work canceling")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202309120307.zis3yQGe-lkp@intel.com/
Signed-off-by: Jens Axboe <axboe@...nel.dk>
