nvmem: change the signature of nvmem_unregister()
We switched the nvmem framework to using kref instead of manually checking the current number of users in nvmem_unregister() so this function can no longer fail. We also converted all remaining users that still checked the return value of nvmem_unregister() to using devm_nvmem_register(). Make the routine return void.
