drm: Nuke SET_UNIQUE ioctl
Ever since commit 2e1868b560315a8b20d688e646c489a5ad93eeae Author: Eric Anholt <anholt@freebsd.org> Date: Wed Jun 16 09:25:21 2004 +0000 DRI trunk-20040613 import the X server supports drm 1.1, thus doesn't call call libdrm's drmSetBusid - the sole user of this ioctl. When reviewing this note that for hilarity both the kernel-internal functions (set_busid) and the libdrm wrapper (drmSetBusid) have names not matching this ioctl (SET_UNIQUE). v2: Polish commit message (Emil).
