[PATCH] f2fs: fix normal discard process

[zhangdongdong]

in the DPOLICY_BG mode,
i + 1 < dpolicy->granularity and i < DEFAULT_DISCARD_GRANULARITY conflict.
if i = 15,The first condition is not met, it will directly enter the
second condition and dispatch all small granularity discards.
The restrictive effect of the first condition will be invalidated.

Fixes: <20ee438232> ("f2fs: issue small discard by LBA order")
