[Nouveau] [PATCH] drm/nouveau/kms/nv50-: Fix CRC-related compile errors with debugfs disabled
Looks like I made the mistake of forgetting to check whether or not this
would build without CONFIG_DEBUG_FS, as the Kbuild bot reported some
issues building with tegra_defconfig:

So, fix the inline function declarations we use in
drm/drivers/gpu/drm/nouveau/dispnv50/crc.h when CONFIG_DEBUG_FS is
enabled.
