QXmlStreamReader: avoid double QHash lookups
Replace
if (hash.contains(x)) { // lookup #1
~~~ hash[x]; // lookup #2
with
if (auto it = hash.find(x); it != hash.end()) { // lookup
~~~ *it; // no lookup
halving the number of QHash lookups. The container is not shared, so
there's no danger of a detach when going directly to the non-const
function.
