[PATCH 4/6] nodedev_hal: Enumerate scsi generic device

[Osier Yang <jyang@xxxxxxxxxx>]

The xml outputed by HAL backend for scsi generic device:

<device>
  <name>pci_8086_2922_scsi_host_scsi_device_lun0_scsi_generic</name>
  <path>/sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/scsi_generic/sg0</path>
  <parent>pci_8086_2922_scsi_host_scsi_device_lun0</parent>
  <capability type='scsi_generic'>
    <char>/dev/sg0</char>
  </capability>
</device>
