ACPICA: nsrepair: handle cases without a return value correctly
Previously acpi_ns_simple_repair() would crash if expected_btypes
contained any combination of ACPI_RTYPE_NONE with a different type,
e.g | ACPI_RTYPE_INTEGER because of slightly incorrect logic in the
!return_object branch, which wouldn't return AE_AML_NO_RETURN_VALUE
for such cases.
Found by Linux Verification Center (linuxtesting.org) with the SVACE
static analysis tool.
