crypto: skcipher - Fix skcipher_dequeue_givcrypt NULL test
As struct skcipher_givcrypt_request includes struct crypto_request at a non-zero offset, testing for NULL after converting the pointer returned by crypto_dequeue_request does not work. This can result in IPsec crashes when the queue is depleted. This patch fixes it by doing the pointer conversion only when the return value is non-NULL. In particular, we create a new function __crypto_dequeue_request that does the pointer conversion.
