IB/mlx5: Report and handle ODP support properly

Browse source

ODP depends on the several device capabilities, among them is the ability
to send UMR WQEs with that modify atomic and entity size of the MR.
Therefore, only if all conditions to send such a UMR WQE are met then
driver can report that ODP is supported. Use this check of conditions
in all places where driver needs to know about ODP support.

Also, implicit ODP support depends on ability of driver to send UMR WQEs
for an indirect mkey. Therefore, verify that all conditions to do so are
met when reporting support.
