[PATCH v2 00/23] Amdgpu plugin cleanups and fixes

This series is a subset of previously posted as RFC:
https://lore.kernel.org/criu/CAEWA0a4ghpPeQjg1ETiQysGj5agfWwJRvMbWzhrYL5r8WZ5H7Q@mail.gmail.com/T/#mfb4ab4866a0cb440961be7170d0e107fab7eedf2

And as v1 cleanups only:
https://lore.kernel.org/criu/[email protected]/T/#md4284ded141876b7d7b942d2d449d6100bd20a2e

It still only contains the fixes and cleanups with the render node hacks
removed.

All patches have now been reviewed, although from v1 to v2 it was a difficult
rebase do upstream movement that happened in the meantime. So I think it would
be good to smoke test it in an environemnt other than where I tested using my
amd_criu IGT.

Two patches have been dropped from the series:

  plugins/amdgpu: Check images were opened successfully
  plugins/amdgpu: Fix error handling in amdgpu_plugin_drm_restore_file()

The same fixes have since been implemented in upstream at least in:

  611af0188dfe ("plugin/amdgpu: add open_img_file error handling")
  16b252ee21a8 ("plugin/amdgpu: add missing xzalloc() NULL checks in drm")

Fingers crossed I have not messed up anything in this relatively extensive
rebase and ideally we can merge this sooner rather than later and carry on
working on top.

v2:
 * Dropped some patches due upstream replicating them etc.
 * Heavy rebase due above.
 * Handled one more incorrect pr_perror.
 * Added newlines to pr_err after the pr_perror conversion.
 * Return error when adding plugin to inventory.
