daemon/io: close LMDB txns after control socket commands

There's the issue that during config-file loading we prefer to do all
changes in rule DB inside a single transaction, so the normal commands
do not close them.  However with control socket commands we can't afford
to leave transactions open (unclear for how long), especially RW transactions.
