Subject: 95iscsi: Do not require network for qla4xxx flash sessions

qla4xxx can store boot sessions in flash, which will then
not show up with iBFT. These boot sesssions will be maintained
by the driver; no specific network configuration is required
here. So suppress network setup for these cases.
