BUG/MEDIUM: htx/cache: use the correct class of error codes on abort

The HTX-specific cache code uses HTX_CACHE_* states which overlap with
the legacy HTTP states. A typo in the error handling made the state
become HTTP_CACHE_END, which equals 3 and is the value for HTX_CACHE_EOD,
which explains why we were seeing a transition to trailers and memory
corruption.

no backport needed.
