kretprobe test patch

Because kretprobe_inst_table is declared as static variable, module program can
not access it. Currently there is no good test method to verify this patch,
here I have to add another test patch to verity it, obviously this method is
awkward.
Without this patch, when kretprobe hit on schedule() function, the allocated
instance sum will be larger than freed instance sum,so there exist memory leak.
