iser-target: Fix flush + disconnect completion handling
ISER_CONN_UP state is not sufficient to know if we should wait for completion of flush errors and disconnected_handler event. Instead, split it to 2 states: - ISER_CONN_UP: Got to CM connected phase, This state indicates that we need to wait for a CM disconnect event before going to teardown. - ISER_CONN_FULL_FEATURE: Got to full feature phase after we posted login response, This state indicates that we posted recv buffers and we need to wait for flush completions before going to teardown. Also avoid deffering disconnected handler to a work, and handle it within disconnected handler. More work here is needed to handle DEVICE_REMOVAL event correctly (cleanup all resources). Squashed: iser-target: Don't deffer disconnected handler to a work Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Cc: <stable@vger.kernel.org> # v3.10+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
