drm/nouveau: fix pm initialization order
If nouveau_pm_perflvl_get() fails, pm->profiles list will be left uninitialized, which causes oops during nouveau_pm_fini(). Move INIT_LIST_HEAD before call to nouveau_pm_perflvl_get(). Signed-off-by: Dmitry Eremin-Solenikov <dmitry_eremin@mentor.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
