[patch] ReiserFS 3.5 support fix

[wtachi]

There are basically three different versions of ReiserFS:

• 3.6. The superblock is at 64K.
• Normal 3.5. The superblock is at 64K.
• Old-layout 3.5. The superblock is at 8K. The bitmap blocks are also placed differently, but we don't care because we don't use them.

The current code doesn't check for normal 3.5, so such filesystems won't be recognized as ReiserFS. This patch fixes that.
