acecc407a5 HellaCache: we do NOT really support probe below the block size! 
If we did, you would somehow have to retain ownership of the
unprobed parts of the block, in case they happened to be dirty.

fa412246b3 Error: don't be an exception wrt. caching 
Prior to this PR, the error device was allowed to be cached by
multiple actors despite never probing any of them. This is a
pretty unusual set of properties that has caused us trouble
several times now in the past.

Let's instead put the Error device into one of two very well
established categories: a straight-up MMIO device or a tracked
memory region.
