relay: fix "full buffer with exactly full last subbuffer" accounting problem
commit 32194450330be327f3b25bf6b66298bd122599e9 upstream
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.
