ACPICA: Fix to handle NULL package elements correctly
Fixed problem where NULL package elements were not returned to
the AcpiEvaluateObject interface correctly. Instead of returning a
NULL ACPI_OBJECT package element, the element was simply ignored,
potentially causing a buffer overflow and/or confusing the caller
who expected a fixed number of elements.
