perf tools: Flush ordered events in case of allocation failure
In previous patches we added a limit for ordered events queue allocation
size. If we reach this size we need to flush (part of) the queue to get
some free buffers.
The current functionality is not affected, because the limit is hard
coded to (u64) -1. The configuration code for size will come in
following patches.
