Revert "bdi: Do not use freezable workqueue"

This reverts commit b30af52. 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. Tashar02: I am not getting any random freeze without this commit. But let's use it to make the workqueu freezable and unbound to save power for our own benefits regardless of the reason for this revert.
