[GIT PULL] more 9p reverts for 6.12-rc5

[Dominique Martinet]

Hi Linus,

- see tip commit (simplify iget revert) for full explanation.
This problem had been ignored for too long and the reverts will also
head to stable (6.9+)
- rebased yesterday to remove the use-folio revert that was applied
directly, but patches are fairly new anyway. I'm confident this set of
patches gets us back to previous behaviour (another related patch had
already been reverted back in April and we're almost back to square 1,
and the rest didn't touch inode lifecycle)

Thanks!
