[PATCH 004 of 7] md: Improve message about invalid superblock during autodetect.

[NeilBrown <neilb@suse.de>]

People try to use raid auto-detect with version-1 superblocks (which
is not supported) and get confused when they are told they have an
invalid superblock.
So be more explicit, and say it it is not a valid v0.90 superblock.
