cifs: dns resolution is needed only for primary channel
When calling cifs_reconnect, before the connection to the server is reestablished, the code today does a DNS resolution and updates server->dstaddr. However, this is not necessary for secondary channels. Secondary channels use the interface list returned by the server to decide which address to connect to. And that happens after tcon is reconnected and server interfaces are requested.
