l-m-c should umount partitions before making filesystems

New situation:

Successfully wrote the new partition table

Re-reading the partition table ...

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)
waiting for partitioning to settle ...done.

/dev/sdh2 is mounted; will not make a filesystem here!

Umounting Partitions

And nothing gets done cause automounter kicked in and mounted /dev/sdh2 in meantime...
