description:
pull up rev 1.37 from trunk (requested by wrstuden):
  In spec_close(), call the device's close routine with the vnode
  unlocked if the call might block. Force a non-blocking close if
  VXLOCK is set.  This eliminates a potential deadlock situation, and
  should eliminate the dirty buffers on reboot issue.
