CA-411988 Fix TypeError in LVHDoHBASR.load() with dynamic module loading (#787)

Replace super() with direct parent class call to fix "TypeError: super(type,
obj): obj must be an instance or subtype of type" when SR.from_uuid()
dynamically loads the module.

This aligns load() with all other methods in the class (create, attach, scan,
probe, detach, delete) which already use direct parent calls.
