Relax the capability check for creating the RDMA RX steering domain
by considering only the capabilities reported by the firmware
as necessary for its creation, which in turn allows RDMA RX creation
over devices with IB link layer as well.

The table_miss_action_domain capability is required only for a specific
priority, which is handled in mlx5_rdma_enable_roce_steering().
The additional capability check for this case is already in place.
