Log message:
vmm(4): allocate reference for vm and vcpu SLISTs
Mischa Peters reported a performance regression in 7.2 when hosting
numerous guests under vmm(4). While iterating through the list of
vms during servicing an ioctl, vmm was triggering excessive wakeup
calls due to hitting zero refcnt.
Much guidance from dlg@ and testing from Mischa. OK mlarkin@.
