Masami Hiramatsu e527c47081 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.
