initramfs-framework: unmount automounts before switch_root
If mounts are left lingering, then after we switch_root, attempts to
modify the block devices will result in an EBUSY with no way to unmount
them. As we're about to switch_root anyways, there isn't much use to
keep anything mounted unless it has the new rootfs.
