afs: Fix off-by-one in afs_rename() expected data version calculation
When afs_rename() calculates the expected data version of the target directory in a cross-directory rename, it doesn't increment it as it should, so it always thinks that the target inode is unexpectedly modified on the server. Fixes: a58823ac4589 ("afs: Fix application of status and callback to be under same lock") Signed-off-by: David Howells <dhowells@redhat.com>
