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.
Fixes: 6e0e99d58a65 ("afs: Fix mmap coherency vs 3rd-party changes")
