f2fs: use new ioprio Macro to get ckpt thread ioprio level

Browse Source 
IOPRIO_PRIO_DATA in the new kernel version includes level and hint,
So Macro IOPRIO_PRIO_LEVEL is more accurate to get ckpt thread
ioprio data/level, and it is also consisten with the way setting
ckpt thread ioprio by IOPRIO_PRIO_VALUE(class, data/level).

Besides, change variable name from "data" to "level" for more readable.
