vnc: fix crash when no console attached
Since commit e99441a3793b5 ("ui/curses: Do not use console_select()")
qemu_text_console_put_keysym() no longer checks for NULL console
argument, which leads to a later crash:
Thread 1 "qemu-system-x86" received signal SIGSEGV, Segmentation fault.

332 } else if (s->echo && (keysym == '\r' || keysym == '\n')) {
