cifs: only update prefix path of DFS links in cifs_tree_connect()
For DFS root mounts that contain a prefix path, do not change them
after failover.
E.g., if the user mounts
//srvA/root/dir1
and then lost connection to srvA, it will reconnect to
//srvB/root/dir1
In case of DFS links, which may resolve to different prefix paths
depending on their list of targets, the following must be supported:
- mount //srvA/root/link/bar
- connect to //srvA/share
- set prefix path to "bar"
- lost connection to srvA
- reconnect to next target: //srvB/share/foo
- set new prefix path to "foo/bar"
In cifs_tree_connect(), check the server_type field of the cached DFS
referral to determine whether or not prefix path should be updated.
