ITS#7515 fix mdb_dbi_open/close

If a DBI handle is opened by a txn that aborts, the DBI handle
should no longer be valid.

This change breaks programs which do:

open DBI_X; abort/reset/failed commit; open DBI_Y; // Now gets the same number as DBI_X close DBI_X; // Correct until this, but now closes DBI_Y use DBI_Y;

I prefer the old behavior. Simpler: If mdb_dbi_open() succeeded, we had a handle to be used in this and future txns, and which could be closed. Other txns might not (yet) see a database for the handle, but that also happened when another process dropped the database.
