RDMA/core: Fix return code when modify_port isn't supported
Improve return code from ib_modify_port() by doing the following:
- Use "-EOPNOTSUPP" instead "-ENOSYS" which is the proper return code
- Allow only fake IB_PORT_CM_SUP manipulation for RoCE providers that
didn't implement the modify_port callback, otherwise return
"-EOPNOTSUPP"
Fixes: 61e0962d5221 ("IB: Avoid ib_modify_port() failure for RoCE devices")
