[PATCH] app/compress-perf: optimize ops pool allocation

[PATCH] app/compress-perf: optimize ops pool allocation

[Raja Zidane]

An array of the size of total operations needed for the de/compression is
reserved for ops while enqueueing, although only first burst_size entries
of the array are used.

Reduce the size of the array allocated.
