Revert "bdi: Do not use freezable workqueue"

This reverts commit c801b7e. Subsequent to 7b74d84 ("Merge 4.14.240 into android-4.14-stable"), this patch causes devices to randomly freeze on downstream kernels. This happens mostly during suspend. Force restarting the device via button combination leaves no ramoops or logs. Signed-off-by: atndko <[email protected]> Signed-off-by: engstk <[email protected]>
