[PATCH v2 2/5] hw/cxl: Drop Back-Invalidate from default CFMW window restrictions

The default CXL Fixed Memory Window restrictions advertised host-only
coherent together with Back-Invalidate.  A window advertising both
simultaneously is undefined behavior per CXL r4.0 9.18.1.3.

Drop Back-Invalidate from the default, leaving device-coherent +
host-only + volatile + persistent.
