block: Correct handling of bottom device misaligment

The top device misalignment flag would not be set if the added bottom
device was already misaligned as opposed to causing a stacking failure.

Also massage the reporting so that an error is only returned if adding
the bottom device caused the misalignment.  I.e. don't return an error
if the top is already flagged as misaligned.
