Grow: don't try to use 'raid_disks' value for a container.
The 'raid_disks' for a container is zero, so subtracting it
from the given raid_disks to get delta_disks doesn't make sense.
Rather set delta_disks to UnSet and set raid_disks to the requested
number of disks. This then gets passed to reshape_super() which
can use it as required.
