F2FS_BLKSIZE and 4096 are both used in f2fs_io for
IO/buffer size, but F2FS_BLKSIZE may confuse user becasue
it may be 4KB, 16KB, so use macro F2FS_DEFAULT_BLKSIZE
to unify F2FS_BLKSIZE and 4096 in f2fs_io, also adjust
"-c" parameters in mkfs man, to be consistent with commit
c35fa8cd75 ("mkfs.f2fs: change -c option description").

When using the f2fs_io tool to set_verity, it will fail as follows:
unisc:/data # ./f2fs_io set_verity file
FS_IOC_ENABLE_VERITY: Inappropriate ioctl for device
this is because commit: 95ae251fe828 ("f2fs: add fs-verity support"),
the passed parameters do not match the latest kernel version.
After patch:
unisoc:/data # ./f2fs_io set_verity file
Set fsverity bit to file
unisoc:/data # ./f2fs_io getflags file
get a flag on file ret=0, flags=verity
Fixes: 95ae251fe828 ("f2fs: add fs-verity support")

Disk quota file is controlled by filesystem quota subsystem, access time
of quota file is almost random, and should be meanless to user, so let's
add noatime to quota file.
Meanwhile, set quota file w/ F2FS_IMMUTABLE_FL instead of FS_IMMUTABLE_FL,
since F2FS_IMMUTABLE_FL is on-disk flag, however FS_IMMUTABLE_FL is in-memory
one.
