[PATCH] hv: use correct order when freeing monitor_pages

[Radim Krčmář]

We try to free two pages when only one has been allocated.
Cleanup path is unlikely, so I haven't found any trace that would fit,
but I hope that free_pages_prepare() does catch it.

 Cc'd stable because the worst-case looks hard to debug.
 Btw. the module can't get unloaded after we successfully connect?
