drm: Reject DRI1 hw lock ioctl functions for kms drivers
I've done some extensive history digging across libdrm, mesa and xf86-video-{intel,nouveau,ati}. The only potential user of this with kms drivers I could find was ttmtest, which once used drmGetLock still. But that mistake was quickly fixed up. Even the intel xvmc library (which otherwise was really good with using dri1 stuff in kms mode) managed to never take the hw lock for dri2 (and hence kms). Hence it should be save to unconditionally disallow this.
