Subject: [PATCH] writeback: fix inode cgroup switching comment

Commit 682aa8e1a6a1 ("writeback: implement unlocked_inode_to_wb
transaction and use it for stat updates") refers to
inode_switch_wb_work_fn() which never got merged.  Switch the comments
to inode_switch_wbs_work_fn().

Fixes: 682aa8e1a6a1 ("writeback: implement unlocked_inode_to_wb transaction and use it for stat updates")
