tracing: Fix selftest function recursion accounting
The test that checks function recursion does things differently if the arch does not support all ftrace features. But that really doesn't make a difference with how the test runs, and either way the count variable should be 2 at the end. Currently the test wrongly fails for archs that don't support all the ftrace features. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
