chao.an 4a559807a5 arch/netdev: try tcp timer in every txavail call 
In the current implementation, the first transmission of the new
connection handshake is depends entirely by tcp_timer(), which will
caused 0.5s - 1s delay each time in connect().

This patch is mainly to improve the performance of TCP handshake.

Original:

nsh> tcp_client
[    1.536100] TCP connect start.
[    2.000200] TCP connect end. DIFF: tick: 4641, 464ms.
[    3.000300] TCP connect start.
[    4.000400] TCP connect end. DIFF: tick: 10001, 1000ms.
[    5.000500] TCP connect start.
[    6.000600] TCP connect end. DIFF: tick: 10001, 1000ms.
[    7.000700] TCP connect start.
[    8.000800] TCP connect end. DIFF: tick: 10001, 1000ms.

Optimized:

[    3.263600] TCP connect start.
[    3.263700] TCP connect end. DIFF: tick: 1, 0ms.
[    4.263800] TCP connect start.
