[BBQ] Only wait when acquiring a buffer if in a sync.
There's no need to do the explicit maxBuffersAcquired check since the
acquireBuffer call will return a status of NO_BUFFER_AVAILABLE if it
can't acquire any more buffers. Therefore, the code can be simplified so
it will return early in most cases if NO_BUFFER_AVAILABLE is returned.
If there was a request to sync the buffer, then we need to wait on a
free buffer and not return early.
Test: BBQ syncs
