Attempt to fix the issue reported by Alan Grimes with DRM_RADEON_TEXTURE
erroring out when it shouldn't. The errno could be changed by usleep() between the ioctl call and the loop check, if a signal was received. This could cause an EAGAIN return from the DRM_RADEON_TEXTURE ioctl to not loop again. Instead of checking errno, check thevalue of ret itself, since it is a saved (and sign-flipped) copy of errno from the ioctl call.
