percpu-refcount: rename percpu_ref_tryget() to percpu_ref_tryget_live()
percpu_ref_tryget() is different from the usual tryget semantics in that it fails if the refcnt is in its dying stage even if the refcnt hasn't reached zero yet. We're about to introduce the more conventional tryget and the current one has only one user. Let's rename it to percpu_ref_tryget_live() so that it explicitly signifies the peculiarities of its semantics. This is pure rename.
