RDMA/cma: Always set static rate to 0 for RoCE
[ Upstream commit 58030c76cce473b6cfd630bbecb97215def0dff8 ]
Set static rate to 0 as it should be discovered by path query and
has no meaning for RoCE.
This also avoid of using the rtnl lock and ethtool API, which is
a bottleneck when try to setup many rdma-cm connections at the same
time, especially with multiple processes.
