lmdb: ITS#8117 better fix.

Browse Source 
LY: This is not required for ReOpenLDAP, because it
is not such issues related to int/long in cmp/dcmp.
But let be more close to origin's sources.

Origin: Don't change mc_dbx because we would need
to undo the change if the txn aborts. Make the fix
(for get) match existing code for put.
