powerpc/eeh: Fix possible null deref in eeh_dump_dev_log()
[ Upstream commit f9bc28aedfb5bbd572d2d365f3095c1becd7209b ]
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.
