weongyo efbcaa065b o change a lock model based on HAL preemption lock to a normal mtx.
Based on the HAL preemption lock there is a problem on SMP machines
  and causes a panic.
o When a device detached the current tactic to detach NDIS USB driver is
  to call SURPRISE_REMOVED event.  So it don't need to call
  ndis_halt_nic() again.  This fixes some page faults when some drivers
  work abnormal.
o it assumes now that URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER is in
  DISPATCH_LEVEL (non-sleepable) and as further work
  URB_FUNCTION_VENDOR_XXX and URB_FUNCTION_CLASS_XXX should be.
