Subject: [PATCH] net-lib.sh:parse_iscsi_root() fix target parsing
For targets with colons in the iSCSI target name:
"iqn.2000-09.com.foo:storage-system.e2000:00000001cm1p1"
the parser was confused with the optional iscsi_iface_name and
iscsi_netdev_name.
This patch reintroduces the old IQN, EUI and NAA parsing and enhances
the fallback parser by checking the LUN for a numerical value.
(cherry picked from commit 36e8ce4fb01824b49697bd0e7ad3ca3c4cfd4297)
