Driver should process the completion queue entries before a connection
resources are freed. While running mixed traffic due to latency, driver
processes the CQE after the connection resources are freed. This fix
processes all the completion queue before the connection resources are
freed.

In iSCSI Boot scenario, when machine is reboot/shutdown phase
the active sessions are not closed. Driver queue cleanup is
done as part of unload and device is disabled.
Sessions are still active, iSCSI commands are issued from
session which comes to driver, as driver cleanup and device
disabled there is kernel stack dump with errors.
Fix is invoking iscsi_session_failure with ISCSI_ERR_INVALID_HOST
on all the active sessions when shutdown routine is called.

When target send a NOP-IN with valid TTT, driver issues a NOP-OUT
and the task was not freed from driver. The task list available for
the session used to run out, and as no more task list were available
no more iSCSI commands were exchanged on that session.

The mgmt_hba_attributes structure declared was not proper and
because of that the FW response returned for the MBX_CMD was not
matching. This issue went unnoticed as mgmt_hba_attribs structure
members were never used in the code path.
This fix of displaying the FW version had to change the mgmt_hba_attrib
structure also. The latest driver will also work with the older FW as
the issue was in the driver declaration.
