Based on the following report from Smatch, fix the potential NULL
pointer dereference check.
tools/perf/util/cs-etm.c:2545
cs_etm__process_auxtrace_info() error: we previously assumed
'session->itrace_synth_opts' could be null (see line 2541)
tools/perf/util/cs-etm.c
2541 if (session->itrace_synth_opts && session->itrace_synth_opts->set) {
2542 etm->synth_opts = *session->itrace_synth_opts;
2543 } else {
2544 itrace_synth_opts__set_default(&etm->synth_opts,
2545 session->itrace_synth_opts->default_no_sample);
^^^^^^^^^^^^^^^^^^^^^^^^^^
2546 etm->synth_opts.callchain = false;
2547 }
'session->itrace_synth_opts' is impossible to be a NULL pointer in
cs_etm__process_auxtrace_info(), thus this patch removes the NULL
test for 'session->itrace_synth_opts'.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
