[PATCH 1/2] xen, libxc: init msix addr/data with value from qemu via hypercall
Accelerated msix entry is initialized to zero when msixtbl_pt_register is
called. This doesn''t match the value from qemu side, although pirq may already
be mapped and binded in qemu side. Kernel will get wrong value when reading
msix info.
