This patch removes enqueue op counter update from the process_op_bit
function where the process is now done in dequeue stage. The original
stats increment was incorrect as they shouldn't have been updated at all
in this function.

A similar fix has been sent to 20.11 LTS stable, in the interest of
time. In that fix, the enqueued stat is still in use, therefore only the
fix to the count increment was necessary.
