qcacmn: Handle Frag with no peer in RX path

While handling a frag with no peer, donot set packet length as this is
already done while handling the fragment before re-injection into the
REO. Without this, qdf_nbuf_set_pktlen will fail while doing a skb_put
on a non-linear packet.
Also, donot use L2 header offset while doing a pull head for the RX frag.
