unpack-trees: detect mismatching number of cache-tree/index entries

Same as the preceding commit, we unconditionally dereference the index's
cache entries depending on the number of cache-tree entries, which can
lead to a segfault when the cache-tree is corrupted. Fix this bug.

This also makes t4058 pass with the leak sanitizer enabled.
