console: Fix exit code for non-cygwin process.

<[email protected]>Date:   Fri Feb 2 13:59:19 2024 +0900    Cygwin: 
console: Fix exit code for non-cygwin process.        If non-cygwin process is 
executed in console, the exit code is not    set correctly. This is because the 
stub process for non-cygwin app    crashes in 
fhandler_console::set_disable_master_thread() due to NULL    pointer 
dereference. This bug was introduced by the commit:    3721a756b0d8 ("Cygwin: 
console: Make the console accessible from    other terminals."), that the 
pointer cons is accessed before fixing    when it is NULL. This patch fixes the 
issue.        Fixes: 3721a756b0d8 ("Cygwin: console: Make the console 
accessible from other terminals.")    Reported-by: Johannes Schindelin
