Cygwin: pty: Fix a possible race issue in initialization of pcon.
- Currently, tty::pcon_start flag is cleared before transfer_input()
in master::write(), however, the code in setup_pseudoconsole()
waits for transfer_input() using tty::pcon_start. This possibly
causes the race issue. The patch fixes this potential issue.
