[PULL,13/28] vnc: Plug minor memory leak in vnc_display_open()

Commit Message

vnc_display_print_local_addr() leaks the Error object when
qio_channel_socket_get_local_address() fails.  Seems unlikely.  Called
when we create a VNC display with vnc_display_open().  Plug the leak
by passing NULL to ignore the error.
