OpenSSL: Fix a memory leak in crypto_ec_key_parse_priv()

Browse source 
The OpenSSL 3.x version of crypto_ec_key_parse_priv using
OSSL_DECODER_CTX missed the call to free the context. Fix it to avoid a
memory leak.

Fixes: 4f4479ef9e ("OpenSSL: crypto_ec_key_parse_{priv,pub}() without EC_KEY API")
