Btrfs: unplug all devices in the unplug call back

For larger multi-device filesystems, there was logic to limit the
number of devices unplugged to just the page that was sent to our sync_page

But, the code wasn't always unplugging the right device.  Since this was
just an optimization, disable it for now.
