Fix pak order when reconnecting to a server.

When /connect to the same server is issued while already connected, an initial call to CL_Disconnect will remove all pak file references
and reset the pak order.
Reordering only occurs through FS_Restart, which in turn is called when checksum feed changes. Because we reconnect to the same server,
checksum feed never changes and pak file order is not restored to server order again. With certain pak file constellations between client/server,
this may result in an inability to load files from paks which are not correctly detected as referenced paks.
