Update cloned volumes QoS settings.

The SolidFire device inherits all settings (including QoS) from
the parent on a clone.  This meant that although we were expecting
QoS to be updated when a clone was issued with a different Volume
Type than the parent volume it was never acted upon.

This change fixes that bug by simply adding the *new* qos settings
to the ModifyVolume call after cloning.
