hw/cxl/cxl-host: Fix segmentation fault when getting cxl-fmw property
QEMU crashes (Segmentation fault) when getting cxl-fmw property via
qmp:
(QEMU) qom-get path=machine property=cxl-fmw
This issue is caused by accessing wrong callback (opaque) type in
machine_get_cfmw().
cxl_machine_init() sets the callback as `CXLState *` type but
machine_get_cfmw() treats the callback as
`CXLFixedMemoryWindowOptionsList **`.
Fix this error by casting opaque to `CXLState *` type in
machine_get_cfmw().
Fixes: 03b39fcf64bc ("hw/cxl: Make the CXL fixed memory window setup a machine parameter.")
