Martin K. Petersen 9504e0864b block: Fix topology stacking for data and discard alignment 
The stacking code incorrectly scaled up the data offset in some cases
causing misaligned devices to report alignment.  Rewrite the stacking
algorithm to remedy this and apply the same alignment principles to the
discard handling.
