Konstantin Belousov 45d72c7d7f vm_fault_copy_entry: accept invalid source pages. 
Either msync(MS_INVALIDATE) or the object unlock during vnode
truncation can expose invalid pages backing wired entries.  Accept
them, but do not install them into destrination pmap.  We must create
copied pages in the copy case, because e.g. vm_object_unwire() expects
that the entry is fully backed.
