EQLX: Extend of snapshot or clone failure 

When creating a volume from a snapshot or cloning an existing
volume the driver first creates a new volume of the original
size, then extends the volume if needed to meet the requested
size. The extend call in these operations were passing the
wrong arguments into the extend_volume call, resulting in an
exception being thrown.
