From: Xin Xiaohui <xiaohui.xin@intel.com>

Now in dev_gro_receive(), if frags[0].size is pulled to 0, memmove is called and
the null page is released. But it's not enough, we should reset size of each frags
left as well. Compared to this, we can have another way to do this, it's not do do
anything at all.
