cifs: fix expand_dfs_referral
Regression introduced in commit 724d9f1cfba. Prior to that, expand_dfs_referral would regenerate the mount data string and then call cifs_parse_mount_options to re-parse it (klunky, but it worked). The above commit moved cifs_parse_mount_options out of cifs_mount, so the re-parsing of the new mount options no longer occurred. Fix it by making expand_dfs_referral re-parse the mount options.
