RDMA/mlx5: Fix calculation of total invalidated pages

Browse source

[ Upstream commit 7919514764 ]

When invalidating an address range in mlx5, there is an optimization to
do UMR operations in chunks.
Previously, the invalidation counter was incorrectly updated for the
same indexes within a chunk. Now, the invalidation counter is updated
only when a chunk is complete and mlx5r_umr_update_xlt() is called.
This ensures that the counter accurately represents the number of pages
invalidated using UMR.
