RDMA/mlx5: Adding remote atomic access flag to updatable flags
[ Upstream commit 2ca7e93bc963d9ec2f5c24d117176851454967af ]
Currently IB_ACCESS_REMOTE_ATOMIC is blocked from being updated via UMR
although in some cases it should be possible. These cases are checked in
mlx5r_umr_can_reconfig function.
