When switching to atomics for handling the busy bit this means we
cannot rely any-longer on the object lock to protect between the
lookup/allocation, the sleep and the actual page busing.
Busy the page also in read mode, directly in
vm_page_alloc()/vm_page_grab() after the lookup/allocation is just
performed.
This will leave the behaviour consistent.
