crypto: stm32 - Remove unused hdev->err field
The variable hdev->err is never read so it can be removed. Also remove a spurious inclusion of linux/crypto.h. Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Tested-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
