IB/core: Ensure an invalidate_range callback on ODP MR

Browse source

No device supports ODP MR without an invalidate_range callback.

Warn on any any device which attempts to support ODP without supplying
this callback.

Then we can remove the checks for the callback within the code.

This stems from the discussion

https://www.spinics.net/lists/linux-rdma/msg76460.html

...which concluded this code was no longer necessary.
