Subject: [PATCH] QCryptographicHash: fix missing EVP_DigestInit_ex() after
 EVP_MD_CTX_reset()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

EVP_MD_CTX_reset() alone is not sufficient. A following
EVP_DigestUpdate() crashes, so re-init the context, too.

Amends 189444d8c4a1384479962e98e699bf1fd2908de8.

Pick-to: 6.5
