Assume each section has 4 segment:
.___________________________.
|_Segment0_|_..._|_Segment3_|
. .
. .
.__________.
|_section0_|
Segment 0~2 has 0 valid block, segment 3 has 512 valid blocks.
It will fail if we want to gc section0 in this scenes,
because all 4 segments in section0 is not dirty.
So we should use dirty section bitmap instead of dirty segment bitmap
to get right victim section.
