Revert "bdi: Do not use freezable workqueue"

Browse Source 
This reverts commit c801b7e6784c67bb2d7d5f4ba0c81d53cbbf1465.

This commit causes devices to randomly freeze on 4.14 and 4.19 kernels.
This happens mostly during suspend. Force restarting the device via button combination leaves no ramoops or logs.
