octeontx2-af: Fix loop in free and unmap counter

[ Upstream commit 6537e96d743b89294b397b4865c6c061abae31b0 ]

When the given counter does not belong to the entry
then code ends up in infinite loop because the loop
cursor, entry is not getting updated further. This
patch fixes that by updating entry for every iteration.
