IB/mlx5: Fix incorrect size of klms in the memory region
commit da343b6d90e11132f1e917d865d88ee35d6e6d00 upstream.
The value of mr->ndescs greater than mr->max_descs is set in the
function mlx5_ib_sg_to_klms() if sg_nents is greater than
mr->max_descs. This is an invalid value and it causes the
following error when registering mr:
mlx5_0:dump_cqe:276:(pid 193): dump error cqe
