For raid{10,01} to properly work pyblock needs to activate and
deactivate the dmraid sets properly. When activating it should activate
the leafs of the tree first. On deactivation it should start with the
root.
device.py - Added an activeMembers attribute that will hold the members
children that are activated by the activate function. On
acitvation the children get activated first. On
deactivation the father goes first and then the children.
This only applies for RaidSet objects.
