xmalloc: make whole pages xfree() clear the order field (ab)used by xmalloc()
Not doing this was found to cause problems with sequences of allocation
(multi-page), freeing, and then again allocation of the same page upon
boot when interrupts are still disabled (causing the owner field to be
non-zero, thus making the allocator attempt a TLB flush and, in its
processing, triggering an assertion).
