OpenSSL: Fix memory leak in HMAC_CTX compatibility wrapper function

Browse source 
Commit 5c9a33702f ('OpenSSL: Clean up
crypto_hash_*() to use a single implementation') added a wrapper
function to allow the new OpenSSL API to be used with older OpenSSL
versions. However, the HMAC_CTX_free() wrapper was incorrectly skipping
the call to HMAC_CTX_cleanup() which is still needed to free the
resources OpenSSL allocated internally.
