app/compress-perf: fix cycle count operations allocation

[ upstream commit 81353ea ]

In cyclecount main_loop function, each iteration it tries to
enqueue X ops, in case Y<X ops were enqueued, the rest of the
X-Y ops are moved to the beginning of the ops array, to preserve
ops order, and next Y ops are allocated for the next enqueue
action, the allocation of the ops occurs on the first Y entries
in the array, when it should have skipped the first X-Y
array entries and allocate the following Y entries.

Fix the allocation by adding the correct offset.
