Subject: drm/nouveau/nvkm: use list_add_tail() when building object tree
Git-commit: 61c1f340bc809a1ca1e3c8794207a91cde1a7c78
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

Fixes resume from hibernate failing on (at least) TU102, where cursor
channel init failed due to being performed before the core channel.

Not solid idea why suspend-to-ram worked, but, presumably HW being in
an entirely clean state has something to do with it.
