net: bcmgenet: fix dma api length mismatch
commit eee577232203842b4dcadb7ab477a298479633ed upstream.
When un-mapping skb->data in __bcmgenet_tx_reclaim(),
we must use the length that was used in original dma_map_single(),
instead of skb->len that might be bigger (includes the frags)
We simply can store skb_len into tx_cb_ptr->dma_len and use it
at unmap time.
