[v2,00/12,qemu] CXL emulation fixes and minor cleanup.

Message

v2:
 - Patch description fixes to correctly refer to g_malloc() either
   with or instead of g_malloc0() depending on the patch.
 - Add missing brackets for QEMU style as reported by checkpatch.
 - Gathered some tags from Fan (thanks!)

This set includes the majority of fixes I currently have queued
up for the CXL emulation. Most have been posted and reviewed
before so this is just rebases of those.

I've included the _STA fix as that's fairly trivial
and didn't seem worth a separate posting. Also included
dropping some pointless g_malloc0() failure handling that
came up in review of Ira's "cxl/cdat: Handle cdat table build errors".

Note the [... qemu] marking above is because we currently use the
[e-mail] list to ensure CXL people notice the
patches and difficulty of distinguishing QEMU vs Kernel patches
was causing some grief for tracking in patchwork.
Hopefully this is unobtrusive enough to not annoy QEMU reviewers!
