lib/iscsi: Remove unused the param conn from iscsi_append_text()

Browse Source 
Previously we might have any possibility to need conn in
iscsi_append_text(), but it is highly unlikely now. Let's remove
the param conn from iscsi_append_text(). This patch includes a
minor simplification not to use rc but return directly.
