Subject: [PATCH] deactivate: stop raid if disk is a member of it

this is useful in cases where the target machine has
a pre-configured RAID setup, as otherwise disko would
wipe the partition tables and create new ones but would
not be able to inform the kernel about it, as the old
raid was still in use.
