crypto: atmel-{sha,tdes} - Propagate error from _hw_version_init()
atmel_{sha,tdes}_hw_version_init() calls atmel_{sha,tdes}_hw_init(), which may fail. Check the return code of atmel_{sha,tdes}_hw_init() and propagate the error if needed. Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
