dccp: Fix panic caused by too early termination of retransmission mechanism

Thanks is due to Wei Yongjun for the detailed analysis and description of this
bug at http://marc.info/?l=dccp&m=121739364909199&w=2

The problem is that invalid packets received by a client in state REQUEST cause
the retransmission timer for the DCCP-Request to be reset. This includes freeing
the Request-skb ( in dccp_rcv_request_sent_state_process() ). As a consequence,
 * the arrival of further packets cause a double-free, triggering a panic(),
 * the connection then may hang, since further retransmissions are blocked.

This patch changes the order of statements so that the retransmission timer is
reset, and the pending Request freed, only if a valid Response has arrived (or
the number of sysctl-retries has been exhausted).

Further changes:
----------------
To be on the safe side, replaced __kfree_skb with kfree_skb so that if due to
unexpected circumstances the sk_send_head is NULL the WARN_ON is used instead.

bnx2: Reinsert VLAN tag when necessary.

In certain cases when ASF or other management firmware is running, the
chip may be configured to always strip out the VLAN tag even when
VLAN acceleration is not enabled.  This causes some VLAN tagged
packets to be received by the host stack without any knowledge that
the original packet was VLAN tagged.

We fix this by re-inserting the VLAN tag into the packet when necessary.
