Sending kill to MDS while it is stuck trying to replay journal causes it to proceed (and give a confusing error about bad journal version) instead of erroring out. The unwanted messages are:

2016-04-30 21:21:40.455902 7f9f83b9d700  4 mds.0.log Journal 300 recovered.
2016-04-30 21:21:40.455929 7f9f83b9d700  0 mds.0.log Journal 300 is in
unknown format 4294967295, does this MDS daemon require upgrade?

To avoid having OSD problems look like MDS problems, let's fix it.
