David Howells 1744a22ae9 afs: Fix mmap ... Fix afs_add_open_map() to check that the vnode isn't already on the list when it adds it. It's possible that afs_drop_open_mmap() decremented the cb_nr_mmap counter, but hadn't yet got into the locked section to remove it. Also vnode->cb_mmap_link should be initialised, so fix that too.
