Log:
Fix for powering off a HP DJ950C during printing. As stated by Ian:
When the printer is turned off the pipe write will cause and error,
which causes lpd to close the device and reopen it to clear the error.
After a short while the device will disappear from the bus but lpd will
have opened the ulpt0 port by then. ulpt_status will check for status
without checking the sc->dying flag and panic the kernel when the device
finally disappears from the bus.
