libflash: Add checking at blocklevel for erase block aligned erase lengths
Currently blocklevel_erase() will let any erase of any size get passed down
to the backend. Not strictly a problem since libflash does do this check
as well, however, not all future backends will.
This is very much a sanity check to save from a likely mistake.
