[PATCH 17/19] staging/lustre/o2iblnd: leak cmid in kiblnd_dev_need_failover

[green]

From: Liang Zhen <liang.zhen@xxxxxxxxx>

cmid created by kiblnd_dev_need_failover should always be destroyed,
however it is not the case in current implementation and we will leak
cmid when this function detected a device failover.
