From: Artemy Kovalyov <artemyko@xxxxxxxxxxxx>
Memory windows are implemented with an indirect MKey, when page fault
event comes for a MW Mkey we need to find MR at the end of the list
of the indirect MKeys by iterating on all items from the first to the
last.
The calculated offset during this process has to be zeroed after the
first iteration or the next iteration will start from a wrong address.
Fixes: db570d7deafb ("IB/mlx5: Add ODP support to MW")
