  Log Message:
  -----------
  kdc: fix AD -> Heimdal x-realm trusts again

The HDB_F_ALL_KVNOS flag is not getting set in _kdc_db_fetch() if
kvno_ptr == NULL.  Fix the conditional to ensure that one of
HDB_F_ALL_KVNOS or HDB_F_KVNO_SPECIFIED is set in the flags field.

Prior to this change cross-realm TGS_REQ failed with KRB5_GENERIC_ERROR
and e-text "encryption key has bad length".  With this change, the
cross-realm TGS_REQ succeeds.
