This field is used to avoid partial write of logical data blocks like
PDUs. However, XLIO supports send buffer "overcommit" now and allows to
push more data to the queue than the send buffer allows.

Use this property of the send buffer to allow a single NVME PDU to exceed
the limitation.

This will save extra field per socket and simplify logic.

Printing a buffer is an unlikely branch, so no need to inline it.

While a socket is locked, it's state cannot be changed and the only
scenario to change the state is to call polling or TCP timers.

In the TX path we don't call timers and polling is called when the send
buffer is full. Therefore, it's enough to check the connection state
under the lock once for non-blocking sockets. For blocking sockets the
check can be moved after the polling, because the connection state
cannot be changed before.

Check for g_b_exit is relevant only for blocking operations, so check it
just before polling.

list_node is always inlined to a class and its offset is known.
Therefore, we can find the object pointer with a single arithmetic
operation and save 8 bytes per list_node.

Remove the list iterator. It's mostly unused and requires special
treatment of the head and tail. Replace it with next() and prev().
