net/mlx5: HWS, prevent rehash from filling up the queues
While moving the rules during rehash, CQ is not drained. The flush
and drain happens only when all the rules of a certain queue have been
moved. This behaviour can lead to accumulating large quantity of rules
that haven't got their completion yet, and eventually will fill up
the queue and will cause the rehash to fail.
Fix this problem by requiring drain once the number of outstanding
completions reaches a certain threshold.
