            nouveau_nvkm_core_ioctl.c

Log Message:
nouveau: fix a "can return -1 to userland" problem.

nvkm_ioctl_del() for some reason converts 0 into 1 return.  this
appears to be a way to avoid having a log printed by nvkm_ioctl()
and to trigger some dead code ("hack" is always NULL afaict.)
after consuming this value convert it back to 0 for ioctl return.
