fs: fix iversion handling
Currently notify_change directly updates i_version for size updates, which not only is counter to how all other fields are updated through struct iattr, but also breaks XFS, which need inode updates to happen under its own lock, and synchronized to the structure that gets written to the log. Remove the update in the common code, and it to btrfs and ext4, XFS already does a proper updaste internally and currently gets a double update with the existing code. IMHO this is 3.13 and -stable material and should go in through the XFS tree.
