6.12-stable review patch. If anyone has any objections, please let me know.

From: Shuhao Fu sfual@cse.ust.hk
commit e4bea919584ff292c9156cf7d641a2ab3cbe27b0 upstream.
In `nouveau_bo_move_prep`, if `nouveau_mem_map` fails, an error code should be returned. Currently, it returns zero even if vmm addr is not correctly mapped.
