migration/block: replace uses of blk_nb_sectors that do not check result
Uses of blk_nb_sectors must check whether the result is negative.
Otherwise, underflow can happen. Fortunately, alloc_aio_bitmap()
and bmds_aio_inflight() both have an alternative way to retrieve the
number of sectors in the file.
