Porting last 2 openSUSE 12.2 changes forward, which seem
to have been missed:
- Add open-iscsi-support-non-root-boot-volume.patch: handle non-
root boot-time iscsi volumes (bnc#630434)
- Add open-iscsi-fix-sysfs-get-value-null.patch: accept "(null)"
password as meaning no password, when using sysfs (bnc#766300)

These changes are also needed on openSUSE:Factory ...
