SQL/ODBC: don't escape a driver string 

We must not try to escape a driver string, the user has to make sure
that everything is correctly escaped when passing a complete driver
string. This fixes a regression from QTBUG-122642.

Pick-to: 6.7
Fixes: QTBUG-123444

databases if no native driver is available.
On Windows, an ODBC driver manager should be installed by default.
On Windows, an ODBC driver manager is installed by default.
For Unix systems, there are some implementations which must be
installed first. Note that every end user of your application is
required to have an ODBC driver manager installed, otherwise the
QODBC plugin will not work.
When connecting to an ODBC datasource, you should pass the name
of the ODBC datasource to the QSqlDatabase::setDatabaseName()
of the ODBC datasource (DSN) to the QSqlDatabase::setDatabaseName()
function, rather than the actual database name.
It's also possible to pass a FILEDSN (*.dsn) filename or a complete
ODBC driver string. When passing a driver string you must make sure,
that all parameters (username, password, ...) are properly escaped.
Passing the username or password through the QSqlDatabase functions,
the escaping is done by the QODBC plugin.
The QODBC Plugin needs an ODBC compliant driver manager version 2.0 or
later. Some ODBC drivers claim to be version-2.0-compliant,
