  Modified files:
    sys/dev/netif/bfe    if_bfe.c 
  - Propagate error code from various bus_dma functions in bfe_dma_alloc.
  - Correctly destroy dmamaps for partially initialised descriptor rings
  in bfe_dma_alloc, if one of the dmamap creations failed.
  - Centralise error handling of bfe_attach in bfe_detach.
  - Move call to bfe_chip_reset in bfe_detach into the device_is_attached
  - Move bus_teardown_intr() and bus_release_resource() from
  bfe_release_resources to bfe_detach; rename the former to bfe_dma_free
  to reflect remaining code.
  - Call bus_dmamem_free only if the pointer is not NULL, set it to NULL
  after it has been destroyed.
  - Do not destroy dmamaps in bfe_stop, do it in bfe_detach.
  - Correct DMA sync directions in bfe_list_newbuf.
