[PATCH v7 3/4] difftool: remove an unnecessary call to strbuf_release()

The `buf` strbuf is reused again later in the same function, so there is no benefit to calling strbuf_release(). The subsequent usage is already using strbuf_reset() to reset the buffer, so releasing it early is only going to lead to a wasteful reallocation.

Remove the early call to strbuf_release(). The same strbuf is already cleaned up in the "finish:" section so nothing is leaked, either.
