mfd: Remove unneeded and dangerous clearing of clientdata
Unlike real i2c-devices which get detached from the driver, dummy-devices get truly unregistered. So, there has never been a need to clear the clientdata because the device will go away anyhow. For the occasions fixed here, clearing clientdata was even dangerous as the structure was freed already.
