Sam Bobroff 234bee8bb3 powerpc/eeh: Fix possible null deref in eeh_dump_dev_log() ...

[ Upstream commit f9bc28aedf ]

If an error occurs during an unplug operation, it's possible for
eeh_dump_dev_log() to be called when edev->pdn is null, which
currently leads to dereferencing a null pointer.

Handle this by skipping the error log for those devices.
