[Bug uprobes/6852] New: unregister_uprobe: handle unmapped probepoint


If the page containing a probepoint has been unmapped, unregister_uprobe()
should refrain from trying to replace the bkpt with the original opcode.  I
think it's sufficient just to call uprobe_validate_vaddr() and act accordingly.
 I'll attach a patch to that effect, but I haven't figured out a good way to
test it (something  with dlclose(), perhaps).
