[IPSEC]: Fix crypto_alloc_comp error checking
The function crypto_alloc_comp returns an errno instead of NULL to indicate error. So it needs to be tested with IS_ERR. This is based on a patch by VicenÁ Beltran Querol. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
