This reverts commit 45e1ade04b4d60fe5df859076005779f27c4c9be.
Since, it causes the following IGT tests to fail:
kms_cursor_legacy@cursor-vs-flip.*
kms_cursor_legacy@flip-vs-cursor.*

I was able to reproduce, that doesn't seem to be the case. They just rely on multiple legacy cursor ioctl calls being able to complete between consecutive flips, which I suppose is broken by always pulling in non-cursor plane state with any cursor plane state changes.
I'll see if I can find a better solution. Meanwhile,

Any information about how those tests fail? Maybe they accidentally rely on the broken behaviour?
FWIW, something like the reverted commit is definitely needed, see https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177#note_1829068 . That MR is blocked by the reverted fix.

Alternatively, here's an incremental fix:
