node-get-boot-device return wrong value for ipminative driver

if we set boot device to 'pxe' network for the machine, run node-get-boot-device command will get 'None' result, but the expect result should be 'net'

    boot_devices.PXE value should match with pyghmi define

    pyghmi ipmicmd.get_bootdev() returns 'network' for pxe boot mode. However
    ipminative defines 'net' as the name, so it does not match with pyghmi
    return value.

    In this patch, we redefine boot_devices.PXE value to 'network' which match
    pyghmi.
