[Nouveau] [PATCH] drm/nouveau/abi16: add missing break in switch statement

[Gustavo A. R. Silva]

Fix the following warning by adding a missing break:

drivers/gpu/drm/nouveau/nouveau_abi16.c: In function 
‘nouveau_abi16_ioctl_getparam’:
drivers/gpu/drm/nouveau/nouveau_abi16.c:202:3: warning: this statement may fall 
through [-Wimplicit-fallthrough=]
   switch (device->info.platform) {
   ^~
drivers/gpu/drm/nouveau/nouveau_abi16.c:217:2: note: here
  case NOUVEAU_GETPARAM_FB_SIZE:
  ^~~~

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
