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")
