[PATCH] cciss: set default raid level when reading geometry fails
This patch sets a default raid level on a volume that either does not support reading the geometry or reports an invalid geometry for whatever reason. We were always setting some values for heads and sectors but never set a raid level. This caused lots of problems on some buggy firmware. Please consider this for inclusion.
