axi4 ToTL: fix decode error arbitration ( #417 )
...
When selecting between error generation on R and real data on R,
correctly calculate the R backpressure.
This bug manifests when a valid request is immediately followed by
an invalid request, wedging the R channel.

axi4 Bundles: add a size calculation helper
...
The old version was wrong.
Inverting before the << has a different width.
This means you end up with high bits set.
