RDMA/cma: Set default GID type as RoCE when resolving RoCE route
As the function name suggests cma_resolve_iboe_route() resolves RoCE route. However, its default GID type is IB_GID_TYPE_IB and not IB_GID_TYPE_ROCE, even though both are mapped to the same enum value. Change default GID type to IB_GID_TYPE_ROCE. cma_iboe_set_mgid() is updated to reflect the RoCEv2 GID check.
