btrfs: fix super block offset in error message in btrfs_validate_super()

Fix the superblock offset mismatch error message in
btrfs_validate_super(): we changed it so that it considers all the
superblocks, but the message still assumes we're only looking at the
first one.

The change from %u to %llu is because we're changing from a constant to
a u64.
