lib/anon_cred.c: Add check for gnutls_calloc

According to the comment above, add check for the return value of gnutls_calloc() and return an error code if it fails.

Fixes: 23efd9990 ("The Diffie Hellman parameters are now stored in the credentials structures. This will allow precomputation of signatures (for DHE cipher suites).")
