[SCSI] bnx2i: use common iscsi suspend queue

Browse Source 
This just has bnx2i use the iscsi_suspend_queue helper.

The suspend works as follows:

When ep_poll has succeeed iscsid will call conn_bind, the LLD will
then call iscsi_conn_bind which will clear the suspend bit.
When ep_disconnect is called (or if there is a conn error) we set
the suspend bit. For the ep_disconnect case I  added a helper
in the previous kernel that will take the session lock to make sure
iscsi_queuecommand/xmit_task is not running and it will set
the suspend bit.
