KVM: selftests: Export vm_vaddr_unused_gap() to make it possible to request unmapped ranges

Browse Source 
Currently, tests can only request a new vaddr range by using
vm_vaddr_alloc()/vm_vaddr_alloc_page()/vm_vaddr_alloc_pages() but
these functions allocate and map physical pages too. Make it possible
to request unmapped range too.
