linux-aio: increasing MAX_EVENTS to a larger hardcoded value
Since commit 6040aedddb5f474a9c2304b6a432a652d82b3d3c "virtio-blk:
make queue size configurable",if the user set the queue size to
more than 128 ,it will not take effect. That's because linux aio's
maximum outstanding requests at a time is always less than or equal
to 128.
This patch simply increase MAX_EVENTS to a larger hardcoded value of
1024 as a shortterm fix.
