jeff 78fd3a94bb Lock reservations with a dedicated lock in each reservation. Protect the 
vmd_free_count with atomics.

This allows us to allocate and free from reservations without the free lock
except where a superpage is allocated from the physical layer, which is
roughly 1/512 of the operations on amd64.

Use the counter api to eliminate cache conention on counters.
