[Bug kprobes/2183] New: kretprobe on schedule() leaks kretprobe_instances

["jkenisto at us dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

When kretprobes are inserted on "schedule" Mao Bibo reported that kretprobe
instances were not recycled properly and their by causing memory leaks.  He
investigated and came up with the attached patch.
                                                                                
I am forwarding it to you guys for  wider review/comments/suggestions to Bibo.
                                                                                
                                                                                
Thanks,
Anil Keshavamurthy
