Rafael J. Wysocki 33ccf4f817 ACPICA: Avoid walking the ACPI Namespace if it is not there 
[ Upstream commit 0c9992315e ]

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.
