This update for open-iscsi fixes the following issues:

Upgrade to upstream version 2.1.2 as 2.1.2-suse (jsc#SES-1081)

- Use openssl for random data generation
- Misspelled socket name might cause confusion to inexperienced user.
- Let initiator name be created by iscsi-init.service.
- iscsi: fix fd leak
- Fix a compiler issue about string copy in iscsiuio
- Fix a compiler issue about writing one byte
- Fix issue with zero-length arrays at end of struct
- Add *iscsi-init.service*

Note that the "*iscsi-init.service*" adds a new systemd service called "*iscsi-init*", that creates
the iSCSI initiator name file */etc/iscsi/initiatorname.iscsi*, if and only if it does not exist.

- Proper disconnect of TCP connection
- Fix SIGPIPE loop in signal handler
- Update iscsi-iname.c
- log:modify iSCSI shared memory permissions for logs
- Sequence systemd services correctly when upgrading
- Ignore iface.example in iface match checks
- Fix type mismatch under musl.
- Add Wants=remote-fs-pre.target for sequencing.
- Fix issue where "iscsi-iname -p" core dumps.
- iscsi-iname: fix iscsi-iname -p access NULL pointer without given IQN prefix
- Fix iscsi.service so it handles restarts better
