libcli smb smb2: Use correct enumeration type

Clang gives the following error:
../../libcli/smb/smb2_signing.c:547:48: error:
   implicit conversion from enumeration type 'gnutls_mac_algorithm_t'
   to different enumeration type 'gnutls_digest_algorithm_t'
   [-Werror,-Wenum-conversion]
   const size_t digest_len = gnutls_hash_get_len(GNUTLS_MAC_SHA256);
~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~~~

Should be using GNUTLS_DIG_SHA256, which is set to GNUTLS_MAC_SHA256.
