[ Upstream commit b61a9071dc72a3c709192c0c00ab87c2b3de1d94 ]
Free the SEV device if later initialization fails. The memory isn't technically leaked as it's tracked in the top-level device's devres list, but unless the top-level device is removed, the memory won't be freed and is effectively leaked.
