Adrian Hunter 0c861b7fb2 perf intel-pt: Fix segfault in intel_pt_print_info() with uClibc ...

commit 5a3d47071f upstream.

uClibc segfaulted because NULL was passed as the format to fprintf().

That happened because one of the format strings was missing and
intel_pt_print_info() didn't check that before calling fprintf().

Add the missing format string, and check format is not NULL before calling
fprintf().
