drm/amdgpu: fix Idle BOs list in VM debugfs status info

amdgpu_debugfs_vm_bo_status_info() prints the "Idle BOs" section by
iterating lists->needs_update, the same list already printed just
above under "Moved BOs". struct amdgpu_vm_bo_status has a dedicated
idle list, populated whenever a BO's state machine settles, but it
was never read here, so genuinely idle BOs never show up in the
debugfs output and the "Idle BOs" section duplicates "Moved BOs"
instead.

Iterate lists->idle for the "Idle BOs" section.
