Nullify the async #PF worker's local "apf" pointer immediately after the point where the structure can be freed by the vCPU. The existing comment is helpful, but easy to overlook as there is no associated code. Update the comment to clarify that it can be freed by as soon as the lock is dropped, as "after this point" isn't strictly accurate, nor does it help understand what prevents the structure from being freed earlier.
