Stop udev before zpool export

In my setup systemd-udevd reproducible locks and prevent exporting the zpool with: pool is busy.

After stopping udev I was able to export the zpool. However shutting it down before rebooting the whole machine should not make it worse. Also much nicer than booting into an "dirty" zpool within initramfs.

I can also reproduce this behavior on Debian Bookwork. Upcoming doc here: #444

I've tried it lately, in my case it wasn't udev

@gmelikov You might share what it caused in your case? Maybe this also works for me.

@stackcoder unfortunately I didn't have time to investigate further, I've just manually imported pools with force on first boot.
