[krb5-auth-dialog] Use g_clear_error (&error) instead of g_error_free (error)

[Guido Günther <guidog src gnome org>]

commit e3bf7f23494478e5225229ea099edc2f52297c7c
Author: Guido Günther <agx sigxcpu org>
Date:   Sat Jun 5 14:46:26 2010 +0200

    Use g_clear_error (&error) instead of g_error_free (error)
    
    so we don't have to check if error is set.
