f2fs-tools uses ioctl BLKSSZGET to get sector_size, however, this ioctl
will return a value which may be larger than 512 (according to the value
of q->limits.logical_block_size), then this will be inconsistent with
the start_sector, since start_sector is got from ioctl HDIO_GETGEO and
is always in 512 size unit for a sector. To fix this problem, just
change the sector_size to the default value when computing with
start_sector. And fix sectors_per_blk as well.
