Ensure that all iSCSI sessions are correctly terminated during shutdown.
* Enhances the changes done by r286226 (D3052).
* Add shutdown post sync event to run after filesystem shutdown
(SHUTDOWN_PRI_FIRST) but before CAM shutdown (SHUTDOWN_PRI_DEFAULT).
* Changes iscsi_maintenance_thread to processes terminate in preference to
reconnect.

r291227:
s/is->is_conn/ic to shorten things a bit.
r291228:
Do not generate PDUs with payload greater than max_data_segment_length.
It is perhaps preferable to have a separate limit for send instead of
reusing the receive limit. I'll discuss with trasz@ and mav@ before
pulling this into head.
r292618:
Add comment to go with r291228.
iscsi's shutdown_pre_sync prio was SHUTDOWN_PRI_FIRST which caused it to
run before other high priority handlers such as filesystems e.g. ZFS.
This meant the iscsi sessions where removed before the ZFS geom consumer
was closed, resulting in a panic from g_access calls on debug kernels
due to negative acr.
Instead use the same as the old iscsi_initiator SHUTDOWN_PRI_DEFAULT-1
which allows it to run before dashutdown etc but after filesystems.

chosen offload module to iscsid(8), and make iscsid(8) not try to negotiate
anything larger than that.

While we don't support MCS, hole in received sequence numbers may mean
only PDU loss. While we don't support lost PDU recovery, terminate the
connection to avoid stuck commands.
While there, improve handling of sequence numbers wrap after 2^32 PDUs.

This is a workaround for Chelsio TOE driver, that does not update socket
buffer size in hardware after connection established, and unless that is
done beforehand, kernel code will stuck, attempting to send/receive full
PDU at once.
