 Log Message:
 specfs changes for PR kern/37717 (raidclose() is no longer called on
 shutdown). There are still problems with device access and a PR will be
 - Kill checkalias(). Allow multiple vnodes to reference a single device.
 - Don't play dangerous tricks with block vnodes to ensure that only one
   vnode can describe a block device. Instead, prohibit concurrent opens of
   block devices. As a bonus remove the unreliable code that prevents
   multiple file system mounts on the same device. It's no longer needed.
 - Track opens by vnode and by device. Issue cdev_close() when the last open
   goes away, instead of abusing vnode::v_usecount to tell if the device is
