devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()
Create an internal-only type matching the current devtmpfs, never register it and have one kernel-internal mount done. That thing gets mounted only once, so it is free to use mount_nodev(). The "public" devtmpfs (the one we do register, and only after the internal mount of the real thing is done) simply gets and returns an extra reference to the internal superblock.
