cifs: define server-level cache index objects and register them
Define server-level cache index objects (as managed by TCP_ServerInfo structs)
and register then with FS-Cache. Each server object is created in the CIFS
top-level index object and is itself an index into which superblock-level
objects are inserted.
The server objects are now keyed by {IPaddress,family,port} tuple.
