- Providing fine-grained malloc statistic by replacing M_DEVBUF with

  module-specific malloc types.  These should help us to pinpoint the
  possible memory leakage in the future.
- Implementing xpt_alloc_ccb_nowait() and replacing all malloc/free based
  CCB memory management with xpt_alloc_ccb[_nowait]/xpt_free_ccb.  Hopefully
  this would be helpful if someday we move the CCB allocator to use UMA
  instead of malloc().
