sky2: propogate rx hash when packet is copied

When a small packet is received, the driver copies it to a new skb to allow
reusing the full size Rx buffer. The copy was propogating the checksum offload
but not the receive hash information. The bug is impact was mostly harmless
and therefore not observed until reviewing this area of code.
