If libxl_create_logfile fails for some reason then libxl__create_qemu_logfile previously just carried on and dereferenced the uninitialised logfile. Check for the error from libxl_create_logfile, which has already logged for us. This was reported as Debian bug #784880.

The first patch is a leftover from the switch to libxl__create_qemu_logfile, and while there it also handles possible errors when opening /dev/null. The second one is a fix for the issues present in do_daemonize. Thanks, Roger.
