IB/cm: Use the source GID index type
Previosuly, cm and cma modules supported only IB and RoCE v1 GID type.
In order to support multiple GID types, the gid_type is passed to
cm_init_av_by_path and stored in the path record.
The rdma cm client would use a default GID type that will be saved in
rdma_id_private.
