gl_tbm: unregister log domain correctly

This patch will solve a SIGABRT issue caused by following step.

1. module_open
2. module_close /* does not set log domain to -1 */
3. module_open  /* does not register log domain
                   because it is not negative value */
4. module_close /* try to free not allocated memory */
