Medium: iscsi: iscsi status fails with open-iscsi with support for flash (bnc#878039)

iscsiadm -m session has additional output:

> iscsiadm -m session
tcp: [4] 10.2.12.1:3260,1 iqn.2011-03.de.suse.hex-10:disk0 (non-flash)

The flash/non-flash breaks the status. The regular expression
needs update.

The change is compatible with the old output too.
