md: reduce CPU wastage on idle md array with a write-intent bitmap
Recent patch titled Reduce CPU wastage on idle md array with a write-intent bitmap. would sometimes leave the array with dirty bitmap bits that stay dirty. A subsequent write would sort things out so it isn't a big problem, but should be fixed nonetheless. We need to make sure that when the bitmap becomes not "allclean", the daemon_sleep really does get set to a sensible value.
