Fix crypto_alloc_comp() error checking.
[IPSEC]: Fix crypto_alloc_comp error checking [ Upstream commit: 4999f3621f4da622e77931b3d33ada6c7083c705 ] 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 Vicenç Beltran Querol. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
