crypto: sun8i-ce - Fix runtime PM imbalance in sun8i_ce_cipher_init
pm_runtime_get_sync() increments the runtime PM usage counter even the call returns an error code. Thus a corresponding decrement is needed on the error handling path to keep the counter balanced. Fix this by adding the missed function call. Signed-off-by: Dinghao Liu <dinghao.liu@zju.edu.cn> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
