RDMA/core: Modify enum ib_gid_type and enum rdma_network_type
Separate IB_GID_TYPE_IB and IB_GID_TYPE_ROCE to two different values, so enum ib_gid_type will match the gid types of the new query GID table API which will be introduced in the following patches. This change in enum ib_gid_type requires to change also enum rdma_network_type by separating RDMA_NETWORK_IB and RDMA_NETWORK_ROCE_V1 values.
