[PATCH] nmtui: show error on connection deactivation failure

[Olivier Gayot <olivier gayot sigexec com>]

When a failure occurs on deactivation of a connection, no error was
shown on the TUI client. It was not obvious if anything was actually
happening after pressing the <Deactivate> button.

This patch shows the error in a dialog just like we do when a failure
occurs on activation of a connection.
