[PATCH 1/2] bnx2i : Fix CMDSN jump issue seen during cable pull test

["Anil Veerabhadrappa" <anilgv@broadcom.com>]

    * Without the fix bnx2i would fail tt->xmit_task() when link is down
    * libiscsi would have already incremented session->cmdsn before calling
      bnx2i's xmit_task() entry point and will just return the command to
      SCSI-ML when xmit_task() fails. libiscsi does not retract the session->cmdsn
      as the command was never sent on wire
    * It is generally good idea for LLD, bnx2i to accept the scsi cmnd/nopout
      and let upper layer timeout and go though normal session recovery process
    * When link is down, unsolicited nopout will not be accepted by bnx2i and
      connection will never enter recovery state. This fix is required for MPIO
      to work corectly
