ACPICA: Debugger: Fix "terminate" command by cleaning up subsystem shutdown logic
ACPICA commit 7e823714911480be47e310fb1b3590d289b9fd99
Segmentation fault can be seen for executing the "terminate" command. This
is because acpi_ut_subsystem_shutdown() is errnously called multiple times.
This patch cleans up acpi_ut_subsystem_shutdown() logics to fix this
issue. Lv Zheng.
