ACPICA: acpiexec/acpinames: Support very large number of ACPI tables
ACPICA commit ca3bd4c5cdc39a9009280032adbbc20f34e94c47
Fix a couple of issues with >40 ACPI tables.
Return exit error for acpinames to enable use with BIOS builds.
The new exported function is used by acpinames. For Linux kernel, this
change is a no-op.
