[PATCH rdma-next v2 3/7] RDMA/core: Remove protection from wrong in-kernel API usage

[Leon Romanovsky]

From: Leon Romanovsky <leonro@xxxxxxxxxx>

The ib_create_named_qp() is kernel verb that is not used for user
supplied attributes. In such case, it is ULP responsibility to provide
valid QP attributes.

In-kernel API shouldn't check it, exactly like other functions that
don't check device capabilities.
