nouveau: fix nv40_perfctr_next() cleanup regression
commit 86d65b7e7a0c927d07d18605c276d0f142438ead upstream.
gcc-6 warns about code in the nouveau driver that is obviously silly:
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c: In function 'nv40_perfctr_next':
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c:62:19: warning: self-comparison always evaluats to false [-Wtautological-compare]
if (pm->sequence != pm->sequence) {
The behavior was accidentally introduced in a patch described as "This is
purely preparation for upcoming commits, there should be no code changes here.".
As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.
This patch restores the original behavior.
