relayfs: fix infinite loop with splice()
Running kmemtraced, which uses splice() on relayfs, causes a hard lock on x86-64 SMP. As described by Tom Zanussi: It looks like you hit the same problem as described here: commit 8191ecd1d14c6914c660dfa007154860a7908857 splice: fix infinite loop in generic_file_splice_read() relay uses the same loop but it never got noticed or fixed.
