commit e27fec66f0a94e35a35548bd0b29ae616e62ec62 upstream.
The dm-integrity target did not report errors in bitmap mode just after creation. The reason is that the function integrity_recalc didn't clean up ic->recalc_bitmap as it proceeded with recalculation.
Fix this by updating the bitmap accordingly -- the double shift serves to rounddown.
