[Bug kprobes/2452] kretprobe spinlock recursive remove

[yanmin dot zhang at intel dot com]

The patch looks like a hack and disables kprobe within the kret handler.

A thorough approach is to change kretprobe_inst table as a list per 
task_struct and delete the spin lock in trampoline_handler, then estimate if 
it's a reentrancy for current task. This approach has better scalability and  
also solve this issue.
