[zircon][kernel][userboot] Prevent kcounter vmo release VmObjectPaged::CreateFromROData moves pages from wired kernel memory into vmos. If those vmos are closed, the pages will be freed. Handle that situation for the kcounter vmos by either unmapping the pages from the kernel aspace or leaking a reference to the created vmo. Also rename CreateFromROData to CreateFromWiredPages and added a parameter indicating whether the vmo should have exclusive access to the pages, to try and make the api clearer. Test: CQ, kcounter Change-Id: Ie139fa74825ffe4191ec4754ab020110ecc9c410
