ACPICA: Avoid walking the ACPI Namespace if it is not there
ACPICA commit b1c3656ef4950098e530be68d4b589584f06cddc
Prevent acpi_ns_walk_namespace() from crashing when called with
start_node equal to ACPI_ROOT_OBJECT if the Namespace has not been
instantiated yet and acpi_gbl_root_node is NULL.
For instance, this can happen if the kernel is run with "acpi=off"
in the command line.
