KVM: Nullify async #PF worker's "apf" pointer as soon as it might be freed
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.
