commit f6b9cc2c5b2133b5a44f54ed307bbe9e1e02e5fc
Author: Lionel Elie Mamane <lio...@mamane.lu>

fdo#80084 file driver PreparedStatement: close previous ResultSet on reexec
This partially reverts commit d87c2c59c9c1d5f5825f355c9eb941fdf95b42f6
"sdbc file driver (Prepared)Statement: created ResultSet owned by *caller*"
From that commit, we keep the part about not reusing the same
ResultSet on reexecution (client code may have disposed it or closed
it), but we revert the part about not closing / disposing the previous
ResultSet on reexecution.
