Remove NULL check for cm_node->listener in i40iw_accept
as listener is always present at this point.
Remove the check for cm_node->accept_pend and related code
in i40iw_cm_event_connected as the cm_node in this context
is only pertinent to active node and cm_node->accept_pend
is always 0.
This fixes the following smatch warnings,
drivers/infiniband/hw/i40iw/i40iw_cm.c:3691 i40iw_accept()
error: we previously assumed 'cm_node->listener' could be null
drivers/infiniband/hw/i40iw/i40iw_cm.c:4061 i40iw_cm_event_connected()
error: we previously assumed 'cm_node->listener' could be null
