Fix chunk_recycle() Valgrind integration.
Fix chunk_recycyle() to unconditionally inform Valgrind that returned
memory is undefined. This fixes Valgrind warnings that would result
from a huge allocation being freed, then recycled for use as an arena
chunk. The arena code would write metadata to the chunk header, and
Valgrind would consider these invalid writes.
