Subject: writeback, cgroup: split out the functional part of inode_switch_wbs_work_fn()
Split out the functional part of the inode_switch_wbs_work_fn() function
as inode_do switch_wbs() to reuse it later for switching inodes attached
to dying cgwbs.
This commit doesn't bring any functional changes.
