Subject: [PATCH] One more ASAN/MSAN cleanup

commit 484931325e7bcecddc6daf1a55c008ddd67497e4 included a
workaround for a 10.5 merge issue that should now be properly
addressed in commit ab4069909d1f8d0c4740b5bd90e1422ce1978187.

buf_chunk_init(): Remove an unnecessary MEM_MAKE_ADDRESSABLE().
We might invoke MEM_UNDEFINED() here, but actually the allocated
memory ought to be guaranteed to be zero-initialized.
