[r300][patch] retry when busy

Hi, The patch makes radeonWaitIrq() try again if -EBUSY is returned. This fixes benchmark 3 4 in progs/demos/gltestperf Benchmark: 3 - ZSmooth Tex Blend Triangles Benchmark: 4 - ZSmooth Tex Blend TMesh Triangles Not an important app, but other apps might run in to this problem. Rune
