Subject: [PATCH] fs/writeback: fix kernel-doc warnings

The kernel test robot reported kernel-doc warnings here:

    fs/fs-writeback.c:1144: warning: Function parameter or struct member 'sb' not described in 'cgroup_writeback_umount'

cgroup_writeback_umount() is missing an argument description, fix it.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202407261749.LkRbgZxK-lkp@intel.com/
