crypto: ccp: Free SEV device if SEV init fails

Browse Source 
[ 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.
