ocfs2: update seq_file index in ocfs2_dlm_seq_next
commit 914eec5e980171bc128e7e24f7a22aa1d803570e upstream.
The following INFO level message was seen:
seq_file: buggy .next function ocfs2_dlm_seq_next [ocfs2] did not
update position index
Fix:
Update *pos (so m->index) to make seq_read_iter happy though the index its
self makes no sense to ocfs2_dlm_seq_next.
