[PATCH 1/2] cciss: set default raid level when reading geometry fails

["Mike Miller (OS Dev)" <mikem@beardog.cca.cpqcorp.net>]

PATCH 1 of 2

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.

Thanks,
mikem
