Bug#1019253: wine: output spurious message 'wine client error'

[Bill Allombert <ballombe@debian.org>]

Package: wine
Version: 7.0~repack-4
Severity: normal

Dear Debian Wine Party,

I run wine with

WINEARCH=win64 WINEPREFIX=$HOME/.wine64 WINEDEBUG=-all 

and starting on juil.  5,  I get error messages like

wine client error:fc: sendmsg: Socket operation on non-socket
or
wine client error:ec: sendmsg: Bad file descriptor

about once every 200 runs of my test suite, 
even though the program behaviour is correct.

(I use wine to run the test-suite of a free software that I build with
mingw64 on linux for generating a windows installer. It is a command line
software that run without issue under wine)

Unfortunately the spurious warning breaks my workflow. 

At the very least when WINEDEBUG=-all, such message whould not be emitted.

Thanks for maintaining wine!
