pmap: Prefer consistent naming for loader tunable
The sysctl knob 'vm.pmap.pv_entry_max' becomes a loader tunable since
7ff48af7040f (Allow a specific setting for pv entries) but is fetched
from system environment 'vm.pmap.pv_entries'. That is inconsistent and
obscure.
This reverts 36e1b9702e21 (Correct the tunable name in the message).
