ocfs2/cluster: Abort heartbeat start on hard-ro devices

Browse source

Currently if the heartbeat device is hard-ro, the o2hb thread keeps chugging
along and dumping errors along the way. The user needs to manually stop the
heartbeat.

The patch addresses this shortcoming by adding a limit to the number of times
the hb thread will iterate in an unsteady state. If the hb thread does not
ready steady state in that many interation, the start is aborted.
