[PATCH] tools:libxl: return tty path for all serials

[PATCH] tools:libxl: return tty path for all serials

[Bob Liu]

When specifying a serial list in domain config, users of
libxl_console_get_tty cannot get the tty path of a second specified pty serial,
since right now it always returns the tty path of serial 0.

I would suggest changing the title to 

  libxl: return any serial tty path in libxl_console_get_tty

Code-wise, this patch looks good to me. It's a valid bug fix that should
be backported.

Please CC Ian and me in your future submissions.
