Subject: [PATCH] ocfs2: Fix super block reserved field offset comment

The offset annotation for s_reserved2 in struct ocfs2_super_block
was incorrect. After the preceding fields:
- s_xattr_inline_size (2 bytes at 0xB8)
- s_reserved0 (2 bytes at 0xBA)
- s_dx_seed[3] (12 bytes at 0xBC)

The actual offset of s_reserved2 is at 0xC8,
when calculating from the start of the structure.

Correct the offset comment from C0 to C8 to reflect the proper
location in the super block structure.
