From: Leon Romanovsky <leonro@xxxxxxxxxxxx>
Device capability bits are exposing what specific device supports from
HW perspective. Those bits are not dependent on kernel configurations
and RDMA/core should ensure that proper interfaces to users will be
disabled if CONFIG_INFINIBAND_ON_DEMAND_PAGING is not set.
Fixes: f4056bfd8ccf ("IB/core: Add on demand paging caps to ib_uverbs_ex_query_device")
Fixes: 8cdd312cfed7 ("IB/mlx5: Implement the ODP capability query verb")
