tests: acpi: always retain dumped ACPI tables in case of error

If IASL wasn't able to parse expected file, test will just
print warning
  "Warning! iasl couldn't parse the expected aml\n"
and remove temporary table dumped from guest.

Typically expected tables are always valid, with an exception
when patchset introduces new tables.
Make sure dumped tables are retained even if expected files
are not valid, so one could have a chance to manualy check new
