selftests/ftrace: Remove unneeded per-test init/cleanup ftrace
Since ftracetest framework calls initialize_ftrace() right before each test and after all tests, we don't need to init/cleanup ftrace for each test case. Just remove such unneeded init/cleanup code because it can increase logfile size. Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
