Johan Hovold 7d976da043 nvmem: core: fix leaks on registration errors 
commit 3360acdf83 upstream.

Make sure to deregister and release the nvmem device and underlying
memory on registration errors.

Note that the private data must be freed using put_device() once the
struct device has been initialised.

Also note that there's a related reference leak in the deregistration
function as reported by Mika Westerberg which is being fixed separately.

Fixes: b6c217ab9b ("nvmem: Add backwards compatibility support for older EEPROM drivers.")
Fixes: eace75cfdc ("nvmem: Add a simple NVMEM framework for nvmem providers")
