tg3: avoid double-freeing of rx data memory
commit 85aec73d595b8847f9c4ea571deb127913f0d508 upstream.
If build_skb fails the memory associated with the ring buffer is freed but
the ri->data member is not zeroed in this case. This causes a double-free
of this memory in tg3_free_rings->... path. The patch moves this block after
setting ri->data to NULL.
It would be nice to fix this bug also in stable >= v3.4 trees.
