Fix not compositing the client's last posted buffer (LP: #1294048, LP: #1294051, LP: #1294053, LP: #1290306)

In single-display cases the number of ready buffers decreases after a buffer is acquired by the rendering operator.
Determine if there will be uncomposited buffers before acquiring a buffer so it works for single and multi display use cases.
