blkdeactivate: also try to unmount /boot on blkdeactivate -u if on top of supported device

There's nothing special about /boot other than it's used during boot.
But when blkdeactivate is called either on all devices or including a
device where the /boot is on top, we should also include this mount
point when doing unmount before deactivation of supported devices.
