winsys/svga: Don't abort on EBUSY errors from execbuffer
This error code typically indicated that a buffer object that was referenced
by the command stream was being used for CPU access by another client.
The correct action here is to retry after a while. Use usleep() until we
have proper kernel support for this wait.
