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.

In some cases,
sr_health_checkfails with:This occurs when
SR.from_uuid()dynamically loads the module, potentially creating separateLVHDoHBASRclass objects in memory. Python's super() validates class identity and fails when the class reference differs from the instance's class.Replace
super(LVHDoHBASR, self).load(sr_uuid)withLVHDSR.LVHDSR.load(self, sr_uuid)This direct parent call bypasses class identity validation and aligns with all other methods(create, detach etc.) in this class.
