Plug the accounting leak for the wired pages when msync(MS_INVALIDATE)
is performed on the vnode mapping which is wired in other address space.

While there, explicitely assert that the page is unwired and zero the
wire_count instead of substract. The condition is rechecked later in
vm_page_free(_toq) already.
