Subject: [PATCH] drivers: rewrite and remove a superfluous parameter.

I noticed there is a superfluous "*hdr" parameter in rtl8xxxu module
when I am trying to fix some bugs for the rtl8192eu wifi dongle. This
parameter can be removed and then gained from the skb object to make the
function more beautiful.
