light: fix becoming primary when logfiles are damaged
...
When logfile replay aborts with an error, becoming primary would be
impossible.
Without this, repair would be only possible by complete destruction
of the resource.
A previous version of this patch introduced
/proc/sys/mars/allow_primary_when_damaged which would complicate
the sysadmin interface. People would be unsure what to do.

lower storage laysers. Thus MARS should not generate that

On slow networks, the generic net_io_timeout is too long if you are
