Public bug reported:
the fwts --dis option can segfault if the ACPICA disassemble emits a
message via AcpiOsVprintf(). This calls the fwts_acpica helper function
that attempts to print to the log file which fails because the fw
pointer is null. This bug is a regression introduced in commit
54f1ef23a1c3bcbea023ddc799dc7d6becf60556. It is fixed by passing the fw
pointer into fwts_acpica before assembly or disassembly of AML code.
