[libvirt] [PATCH] libxl: initialize vfb defbools in libxlMakeVfb

[Olaf Hering]

If the domU configu has sdl enabled libvirtd crashes:
libvirtd[5158]: libvirtd: libxl.c:343: libxl_defbool_val: Assertion `!libxl_defbool_is_default(db)' failed.

Initialize the relevant defbool variables in libxl_device_vfb.
