RDMA/core: Rename rdma_route.num_paths field to num_pri_alt_paths
This fields means the total number of primary and alternative paths,
i.e.,:
0 - No primary nor alternate path is available;
1 - Only primary path is available;
2 - Both primary and alternate path are available.
Rename it to avoid confusion as with follow patches primary path will
support multiple path records.
