net: remove redundant code in dev_hard_start_xmit()

Browse Source 
This reverts commit 068a2de57d (net: release dst entry while
cache-hot for GSO case too)

Before GSO packet segmentation, we already take care of skb->dst if it
can be released.

There is no point adding extra test for every segment in the gso loop.
