octeontx2-af: Fix loop in free and unmap counter

Browse Source 
[ Upstream commit 6537e96d74 ]

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.
