Move the IN_USE clear in net_tcp_release() to the END of the function
after the destruction is complete so someone else doesn't allocate it
while we're still cleaning it up.
Also, operations on the IN_USE flag need to be atomic for correctness.
Stick an irq_lock() around them.

Big chunks of this struct were essentially unused:
+ The prev_state field was stored at state change but never inspected.
+ The send_wnd, send_max_wnd, send_cwnd, send_pcount and
send_ss_threshold fields were simply unused.
+ The recv_scale field was never initialized to anything but zero,
remove the support. Windows greater than 64k seem very unlikely to
be useful to Zephyr anyway; if we actually want window scaling (in
either direction -- there are large memory costs!) it should
probably be optional via Kconfig. We surely don't want to carry
this for all builds.
+ The buf_max_len field was hard-coded static, replace with a #define
+ Double-memset of the ack_timer field in initialization

Reason for error is ARP message redirected back to ethernet
instead of sending directly.
Call flow:
ehternet_send()
net_arp_prepare()
net_send_data().. which again calls ethernet_send().
So below check is necessary in net_arp_prepare().
"if (ntohs(hdr->type) == NET_ETH_PTYPE_ARP)".
When same buffer used for Tx, it still contains garbage in link
layer header (which is uninitialized). But this check
assumes buffer is ARP and send it immediately.
So first fix is just queue the Tx buf with net_if_queue_tx.
Now only ethernet_send() will call net_arp_prepare(), means
input buffer for net_arp_prepare is not ARP at all. So the check
is not necessary.

While testing SLIP driver, I found out that after some packets, the
ethernet L2 was getting the eth hdr pointer 14 bytes behind the proper
place. That's because at some point the slip driver got a buf which had
been used already, and thus had a ll_reserve value set from previous
usage. That's bad, so let's make sure ll_reserve is 0 when we take a
buffer. (Note that ll_reserve and reserver_head is much different at
this point).
