Hi,
I need some help regarding an issue I am facing.
I was trying some stuff by initializing a machine that I added using
machine_init. The corresponding file was added in the build infra and gets
compiled correctly.
However, i do not see the same getting initialized in the
register_module_init me
Coverity reports the 'size' may be used uninitialized, but that can't happen,
because the caller has checked "if (binfo->dtb_filename || binfo->get_dtb)"
before call 'load_dtb'.
Here we simply remove the 'if (binfo->get_dtb)' to satisfy coverity.

The original checks missed the invalid bound value, which will lead
possible out of bounds read in the follow codes.

If QEMU is started with -numa ... Windows only notices that
CPU has been hot-added but it will not online such CPUs.
It's caused by the fact that possible CPUs are flagged as
not enabled in SRAT and Windows honoring that information
doesn't use corresponding CPU.
