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.
