staging:r8188eu: update pkt->(data|tail|len) synchronously with rx_(data|tail|len) in recv_frame structure
Original driver code uses rx_* members to store skb (pkt) fields
(instead of pkt->* members), pkt->* updated only after data
completely formed, not in process.
Update pkt->* after data buffer changed (with rx_*).
