    qemu-char: don't issue CHR_EVENT_OPEN in a BH

we had no echo by default with -nographic, and it gave
the prompt when switching to monitor:

  $ qemu-system-x86_64 -nographic
  _

(nothing is on the screen except the command line)

  (Ctrl+A, c)
  QEMU 1.5.0 monitor - type 'help' for more information
  (qemu) _

After this patch, we now have:

  $ qemu-system-x86_64 -nographic
  QEMU 1.5.0 monitor - type 'help' for more information
  (qemu)
  _

(note the cursor position on the _next_ line after the prompt),
and the system is actually in "serial port" mode, not monitor
mode (you still need to hit Ctrl+A,c to switch to monitor).

Thanks,

/mjt
