ext{3,4}: Fix potential race when setversion ioctl updates inode
The EXT{3,4}_IOC_SETVERSION ioctl() updates i_ctime and i_generation without i_mutex. This can lead to a race with the other operations that update i_ctime. This is not a big issue but let's make the ioctl consistent with how we handle e.g. other timestamp updates and use i_mutex to protect inode changes.
