Fix PV CPUID virtualization of XSave

The patch will fix XSave CPUID virtualization for PV guests. The XSave
area size returned by CPUID leaf D is changed dynamically depending on
the XCR0. Tools/libxc only assigns a static value. The fix will adjust
xsave area size during runtime.

Note: This fix is already in HVM cpuid virtualization. And Dom0 is not
affected, either.
