Subject: [PATCH 1/4] hcnmgr: Avoid cleanup of bond interface at boot time when
 no HNV exists

References: bsc#1181956 ltc#190722
Upstream: accpeted, expected v1.3.9
Git-commit: 0b59d4a372aa266caa75f3b6a253b8f5aeaf3802

At boot time, hcn scans the device tree and discovers if there was a new
HNV being added while lpar was inactive. It also cleans up the old hnv
interfaces. This patch avoids cleaning up bonding interface when no HNV
network devices exists.
