From: Steven Rostedt <rostedt@goodmis.org>
The function call_filter_check_discard() has been removed in the
commit 49e4154f4b16 ("tracing: Remove TRACE_EVENT_FL_FILTERED logic"),
from another topic branch. But when merged together with commit
21e92806d39c6 ("function_graph: Support recording and printing the
function return address") which added another call to
call_filter_check_discard(), it caused the build to fail. Since the
function call_filter_check_discard() is useless, it can simply be removed
regardless of being merged with commit 49e4154f4b16 or not.
