f2fs_io has been modified for testing, the length for fiemap is
real
f2fs_is_atomic_file(inode) is checked in f2fs_defragment_range,
so remove the redundant checking in f2fs_ioc_defragment.

Dear Chao,
any suggestions about this patch version? base your kindly suggestions
on patch v1
this is the issue encountered when I test GC.
thanks!

F2FS_BLKSIZE may be 4KB, 16KB, so use F2FS_BLKSIZE to replace
some hardcode desc about unit in some f2fs_io cmd, also
adjust "-c" parameters in mkfs man, to be consistent with
commit c35fa8cd75ac ("mkfs.f2fs: change -c option description").
