f2fs: introduce sysfs/data_io_flag to attach REQ_META/FUA
This patch introduces a way to attach REQ_META/FUA explicitly
to all the data writes given temperature.
-> attach REQ_FUA to Hot Data writes
-> attach REQ_FUA to Hot|Warm Data writes
-> attach REQ_FUA to Hot|Warm|Cold Data writes
-> attach REQ_FUA to Hot|Warm|Cold Data writes as well as
REQ_META to Hot Data writes
