Do not decrement the number of VMs counter twice in one of vm_create()
error paths. If creation of the first VM fails, the counter will wrap
around to a huge value. The same value could later be passed to malloc()
through vm_get_info() causing a panic.
While here, only decrement the same counter in vm_teardown() if the VM
has a valid ID. Otherwise it has not been accounted for.
