[PATCH] Fix EMI unacked message detection in windowing mode

[Olivier Dormond]

Hello,

 Here is a patch against 1.4.3 to fix the detection of non-acked
messages sent through EMI/UCP. The problem arise when the window
parameter is set to a non-default value. In this case the loop in 
emi2_idleprocessing which search for unacked messages only examine
the first "window" messages of the ring-buffer and thus misses any
unacked message with a trn higher then "window".

Cheers,

                                Olivier
