kernel - Fix panic/crash in vm_object_page_remove()
* When vm_object_page_remove() is called with one page, the caller is allowed
to hold a spinlock (typically on that page). The callback is not supposed
to call user_yield in that situation.
* Fix missing initialization of info.count which could result in the callback
issuing a yield when it was not supposed to.
