From: Sascha Hauer <s.hauer@pengutronix.de> commit ef5aafb6e4e9942a28cd300bdcda21ce6cbaf045 upstream. set_seen() sets the bit corresponding to the PEB number in the bitmap, so when self_check_seen() wants to find PEBs that haven't been seen we have to print the PEBs that have their bit cleared, not the ones which have it set.
