[Xitami-Dev] read_TCP returns 0 instead of -1

[D'Hoye, Peter]

Rafael,

thanks for this obvious fix. I'm using LRWP to create
a web-interface for a machine we make, and I saw the
LRWP client go in a loop when Xitami was restarted.
I didn't have any time to investigate, thanks to you
I can scratch another bug from my to-do list :-)

PS: Pieter, we all mis Liberetto !!!
