If there is no way to write a test for this, can you add a comment so that nobody accidentally moves this around again?

AFAICT a regression test is simple: d:\code\node-master$ setNODE_CHANNEL_FD=0
d:\code\node-master$ node
child_process.js:107
p.open(fd);
^

There's a regression test and git blame, so I don't think it's necessary (or even useful in this form tbh).

No need to backport since #16141 isn't an issue on v6.x AFAIK. |

Initializing IOCP on the same fd twice can fail on Windows.
Consequently, if the IPC channel uses fd 1 or 2 and the console is setup
first, writing to the IPC channel will fail.
Fixes: #16141
Will add a test if there are no objections to this approach.
