drm/nouveau: omit to create schedulers using the legacy uAPI

Browse Source 
Omit to create scheduler instances when using the legacy uAPI. When
using the legacy NOUVEAU_GEM_PUSHBUF ioctl no scheduler instance is
required, hence omit creating scheduler instances in
nouveau_abi16_ioctl_channel_alloc().
