crecord: add error reporting for failure in curses interface initialization

Before this patch, we couldn't report to the user any error that occurred:
- after we enabled the curses interface but
- before the interface is set up and drawn
This patch, provides a way to set errors that happens during the initialization
of the interface and log them once the curses interface has been displayed.
