RDMA/mlx5: Enable ATS when allocating kernel MRs

Browse source

When creating kernel MRs, it is not definitive whether they will be used
for peer-to-peer transactions or for other usecases, since address
mapping is performed only after the MR is created.

Since peer-to-peer transactions benefit significantly from ATS
performance-wise, enable ATS on newly-allocated kernel MRs when
supported.
