Eliminate two calls to vm_page_xunbusy() that are both unnecessary and
incorrect from the error cases in exec_map_first_page().  They are
unnecessary because we automatically unbusy the page in vm_page_free()
when we remove it from the object.  The calls are incorrect because they
happen after the page is freed, so we might actually unbusy the page
after it has been reallocated to a different object.  (This error was
introduced in r292373.)
