make some optimizations for http_conn.go

[Tovi163]

This operation is performed twice，”c.rwc.(*bfe_tls.Conn) “

Better to test cover them :-)

这里的初始值可能是错的。

合理的做法：

• A. 暂保持未知值（在不影响其它功能的前提下，等到合适的时机设置）
• B. 采用以下方式判断

tlsConn, isTlsConn := c.rwc.(*bfe_tls.Conn)
if !isTlsConn {
     c.session.Proto = "http"
}

这里设置初始值也有可能是错的.

建议：

1. 将line 320 移动到 line 381
2. if 条件改为 if isTlsConn
