[PATCH 1/1] conhost: Fix tests on ReadConsole with CONSOLE_READCONSOLE_CONTROL.

[Eric Pouech]

From: Eric Pouech

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52648

The patch should fix the errors around line 1370 in conhost/tests/tty.c,
but it doesn't fix other errors around line 1530 and 1550 which are
completly unrelated to this change.
So failures to be expected on the later.
