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.
