RDMA/ucma: Use rdma cm API to query GID

Browse source

Make use of rdma_read_gids() API to read SGID and DGID which returns
correct GIDs for RoCE and other transports.

rdma_addr_get_dgid() for RoCE for client side connections returns MAC
address, instead of DGID.
rdma_addr_get_sgid() for RoCE doesn't return correct SGID for IPv6 and
when more than one IP address is assigned to the netdevice.

Therefore use transport agnostic rdma_read_gids() API provided by rdma_cm
module.
