Windows: Fix bufferFromAttribute for QBluetoothUuids

In the past a QVariant's typeId was QMetaType::UserType if it contained
a QBluetoothUuid. This is no longer the case, so handling of
QBluetoothUuid and co has to happen inside the "default" condition of
the switch statement.

As a flyby an unused variable was removed.
