Since f2fs support large sector size in commit 55cf9cb63f0e "f2fs: support large
sector size", block device with sector size of 512/1024/2048/4096 bytes can be
supported.
But mkfs.f2fs still use default sector size: 512 bytes as sector size, let's fix
this issue in this patch.
v2:
o remove unneeded printed message when sector size is large than 512 bytes
suggested by Kinglong.
o show correct sector size in printed message.
o use config.sectors_per_blk instead of DEFAULT_SECTORS_PER_BLOCK suggested by
Kinglong.

This "512bytes" should be modified as above too.
