Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/nouveau/dispnv50/disp.c: In function 'nv50_mstm_cleanup':
drivers/gpu/drm/nouveau/dispnv50/disp.c:1389:6: warning:
variable ‘ret’ set but not used [-Wunused-but-set-variable]

drivers/gpu/drm/nouveau/dispnv50/disp.c: In function 'nv50_mstm_prepare':
drivers/gpu/drm/nouveau/dispnv50/disp.c:1413:6: warning:
variable ‘ret’ set but not used [-Wunused-but-set-variable]

It never used since introduction.
