tcp: prevent timer handler being called frequently
In the current implement, tcp would start or up an one tick
retransmit timer for that connection if vlib_buffer_alloc()
return 0. Now the tick is 0.1ms, this means that if VPP is
in a buffer shortage state, there would be a large number of
burst timer expirations.
This commit limits the minimum interval of the retransmission
timer to 100ms.
Type: fix
