IB/mlx5: Fix MR registration flow to use UMR properly
[ Upstream commit e5366d309a772fef264ec85e858f9ea46f939848 ]
Driver shouldn't allow to use UMR to register a MR when
umr_modify_atomic_disabled is set. Otherwise it will always end up with a
failure in the post send flow which sets the UMR WQE to modify atomic access
right.
Fixes: c8d75a980fab ("IB/mlx5: Respect new UMR capabilities")
