[PATCH] nvmem: core: Prevent memory leak when device is unregistered

[Mika Westerberg]

The nvmem_unregister() calls device_del() for the device but forgets to
call put_device() to actually release the device object which causes
that memory to be leaked.

Fix this by calling device_unregister() for the device intead which also
calls put_device() for the device releasing it eventually.
