cifs: fix issue mounting of DFS ROOT when redirecting from one domain controller to the next
This patch fixes an issue when cifs_mount receives a STATUS_BAD_NETWORK_NAME error during cifs_get_tcon but is able to continue after an DFS ROOT referral. In this case, the return code variable is not reset prior to trying to mount from the system referred to. Thus, is_path_accessible is not executed and the final DFS referral is not performed causing a mount error. Use case: In DNS, example.com resolves to the secondary AD server ad2.example.com Our primary domain controller is ad1.example.com and has a DFS redirection set up from \\ad1\share\Users to \\files\share\Users. Mounting \\example.com\share\Users fails. Regression introduced by commit 724d9f1.
