David Howells 76f6777c9c pipe: Fix iteration end check in fuse_dev_splice_write() ...

Fix the iteration end check in fuse_dev_splice_write().  The iterator
position can only be compared with == or != since wrappage may be involved.

Fixes: 8cefc107ca ("pipe: Use head and tail pointers for the ring, not cursor and length")
