[PATCH V3 07/11] Skip clustered devices in incremental

[Guoqing Jiang <gqjiang@suse.com>]

We want the clustered devices to be started exclusively by a cluster
resource-agent. So, avoid starting using the incremental option.

This also skips a clustered md from starting during boot in inactive mode.
