cifs: change iface_list from array to sorted linked list
A server's published interface list can change over time, and needs
to be updated. We've storing iface_list as a simple array, which
makes it difficult to manipulate an existing list.
With this change, iface_list is modified into a linked list of
interfaces, which is kept sorted by speed.
Also added a reference counter for an iface entry, so that each
channel can maintain a backpointer to the iface and drop it
easily when needed.
