debug: use dev_WARN() rather than WARN_ON() in device_pm_add()
device_pm_add() has a WARN_ON that is showing relatively high on
kerneloops.org, but unfortunately the WARN_ON is less than useful
in that it doesn't print any information about what device is causing
the issue.
This patch fixes this by turning the WARN_ON() into the newly
introduces dev_WARN() which will print information about the
device in question.
