MIPS: Tracing: Enable HAVE_FUNCTION_TRACE_MCOUNT_TEST for MIPS
There is an exisiting common ftrace_test_stop_func() in
kernel/trace/ftrace.c, which is used to check the global variable
ftrace_trace_stop to determine whether stop the function tracing.
This patch implepment the MIPS specific one to speedup the procedure.
Thanks goes to Zhang Le for Cleaning it up.
