virsh: Don't reconnect after the command when disconnected

Each command that needs a connection causes a new connection to be
made.  Reconnecting after a command failed is pointless, mainly when
there is no other command to run.  Removeing three lines of code takes
care of that and keeps virsh working as it should.
