swrast: use better _swrast_compute_lambda() function
The MAX-based function can produce values that are non-monotonic for a span which causes glitches in texture filtering. The sqrt-based one avoids that. This is perhaps slightly slower than before, but the difference probably isn't noticable given we're doing software mipmap filtering. Issue reported by Nir Radian <nirr@horizonsemi.com>
