QPSQL: Fix crash when a prepared statement is deleted after the db was removed
When a prepared statement is still alive after the database was removed
with QSqlDatabase::removeDatabase(), the cleanup routine is trying to
access the driver which is no longer alive which results in a crash.
Fix it by checking if the driver is still alive similar to
