cifs: distribute channels across interfaces based on speed
Today, if the server interfaces RSS capable, we simply
choose the fastest interface to setup a channel. This is not
a scalable approach, and does not make a lot of attempt to
distribute the connections.
This change does a weighted distribution of channels across
all the available server interfaces, where the weight is
a function of the advertised interface speed.
Also make sure that we don't mix rdma and non-rdma for channels.
