deferは実行された時点の構造体などの情報を積んでしまうので、forの中で利用するのは良くない場合があります
deferはfuncのスコープでしか実行されないので、即時関数でforの中身を囲うなどで対処可能です

http.Clientはsafe for concurrentですので、どこかで一つつくっておくだけでも十分です
また、Transportはnilであった場合、DefaultTransportが利用されるので、 client := new(http.Client) だけでも問題なく利用できます

// Transport specifies the mechanism by which individual // HTTP requests are made. // If nil, DefaultTransport is used. Transport RoundTripper

上記でCancelRequestを呼ぶために生成しているのかもしれませんが、すでにdeprecatedですので、WithContextを利用したほうが良いです
https://golang.org/pkg/net/http/#Transport.CancelRequest
Deprecated: Use Request.WithContext to create a request with a cancelable context instead.
