block: do not directly set total_sectors
To prepare for expressing block sizes in bytes instead of sector counts,
this patch replaces all direct assignments of bs->total_sectors.
This converts the expression `bs->total_sectors = X` (where X is sector
count) to `bdrv_setlength(bs, BDRV_SECTOR_SIZE * X)`.
Expressions such as `bs->total_sectors = Y / 512` are changed to
`bdrv_setlength(bs, BDRV_SECTOR_SIZE * (Y / 512))` to account for the
floor division change. If these conditions can be relaxed, it will be
done in the future.
