From: Avihai Horon <avihaih@nvidia.com>

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.
