relay: fix "full buffer with exactly full last subbuffer" accounting problem
In relay's current read implementation, if the buffer is completely full but hasn't triggered the buffer-full condition (i.e. the last write didn't cross the subbuffer boundary) and the last subbuffer is exactly full, the subbuffer accounting code erroneously finds nothing available. This patch fixes the problem.
