3/3 from the next series removes the extra get_uprobe() + put_uprobe().

Initially the change said something like

	This patch adds the additional get_uprobe/put_uprobe into _register,
	the next patch will remove this.

But then decided to split this "next" patch and send it in another series.

Oleg.
