drm/nouveau: clear output poll workers before nouveau_fbcon_destroy()
Resources needed for output poll workers are destroyed in
nouveau_fbcon_fini() before output poll workers are cleared in
nouveau_display_fini(). This means there is a time between fbcon_fini()
and display_fini(), where if output poll happens, it crashes.
This patch introduces another output poll clearing before fbcon
resources are destroyed.
BUG: KASAN: use-after-free in
__drm_fb_helper_initial_config_and_unlock.cold+0x1f3/0x291
