block: implement bdrv_co_is_allocated() boundary cases

Cases beyond the end of the disk image are only implemented for block
drivers that do not provide .bdrv_co_is_allocated().  It's worth making
these cases generic so that block drivers that do implement
.bdrv_co_is_allocated() also get them for free.
