add iscsi_force_reconnect()

Browse Source 
If a connection attempt is hung, then iscsi_reconnect() won't do anything. This
makes sense if we'd just re-try to connect to the same target, but if (for
example) login redirect might point us to a different, healthy, target, it
should be possible to restart the full connection process on request.
