Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.
Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.
Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.
This patch doesn't add any new functionality.

Current code didn't modify the QP state to error because it queried the
QP state as a bitmap while it isn't. So the code never got executed.
This patch fixes this and queries for each QP state respectively and not
at once via a bitmask.

Add struct ib_udata to the signature of create_ah callback that is

This patch prepares the ground for mlx5 driver to resolve destination
