QSqlRelationalDelegate: compile with QT_NO_CAST_FROM_BYTEARRAY

QSqlRelationalDelegate::setEditorData() does not compile when
QT_NO_CAST_FROM_BYTEARRAY is defined. Since it's a public header this
will break user code.
Fix it by calling QByteArray::data() instead of relying on the
implicit cast.

Fixes: QTBUG-72764
