platform/x86/intel/ifs: Trace on all HT threads when executing a test
Enable the trace function on all HT threads. Currently, the trace is
called from some arbitrary CPU where the test was invoked.
This change gives visibility to the exact errors as seen by each
participating HT threads, and not just what was seen from the primary
thread.
Sample output below.
