    heimdal: Fix CID 1273430 Double free
    
    I think Coverity is right here: Before the preceding call to
    krb5_make_principal we already krb5_free_principal(ctx, tmp_creds.server)
    without wiping out tmp_creds.server. The call to krb5_make_principal only
    stores something fresh when it also returns 0 a.k.a. success.
