Subject: [PATCH v2 2/2] workqueue: Increase worker desc's length to 32

Commit 31c89007285d ("workqueue.c: Increase workqueue name length")
increased WQ_NAME_LEN from 24 to 32, but forget to increase
WORKER_DESC_LEN, which would cause truncation when setting kworker's
desc from workqueue_struct's name, such as usage in process_one_work().

Fixes: 31c89007285d ("workqueue.c: Increase workqueue name length")

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202405131400.sEYZHYk2-lkp@intel.com/
