Subject: [PATCH] read-cache: fix leaking hash context in `do_write_index()`

When writing an index with the EOIE extension we allocate a separate
hash context. We never free that context though, causing a memory leak.
Plug it.

This leak is exposed by t9210, but plugging it alone does not make the
whole test suite pass.
