This converts pipefs to use the new scheme. Here we're calling iunique to get
a unique i_ino value for the new inode, and then hashing it afterward. We
call iunique with a max_reserved value of 1 to avoid collision with the root
inode. Since the inode is now hashed, we need to take care that we end up in
generic_delete_inode rather than generic_forget_inode or we'll create a nasty
leak, so we clear_nlink when we destroy the pipe info.
