ACPICA: Disassembler: Do not unconditionally remove temporary names
ACPICA commit c46f496df41e53a368f877f88b70bdfc9bd6fdbe
Change the Switch disassembly code to check if the conversion can be
done before removing temporary (_T_x) names. Prevents invalid
disassembly of AML created by older compilers (circa 2005).
