[PATCH] node_device_udev: add error reporting to udevProcessCCWGroup

[Boris Fiuczynski <fiuczy@xxxxxxxxxxxxx>]

Add reporting an internal error when the string to type conversion of
devtype fails as this indicates a serious problem since devtype was used
to get into this method during the udev event handling.
