tracing: Use cpumask_available() to check if cpumask variable may be used
This fixes the following clang warning: kernel/trace/trace.c:3231:12: warning: address of array 'iter->started' will always evaluate to 'true' [-Wpointer-bool-conversion] if (iter->started) Link: http://lkml.kernel.org/r/20170421234110.117075-1-mka@chromium.org Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
