yohan.joung d26fecb03e f2fs: prevent the current section from being selected as a victim during GC 
When selecting a victim using next_victim_seg in a large section, the
selected section might already have been cleared and designated as the
new current section, making it actively in use.
This behavior causes inconsistency between the SIT and SSA.

F2FS-fs (dm-54): Inconsistent segment (70961) type [0, 1] in SSA and SIT

issue scenario
segs_per_sec=2
- seg#0 and seg#1 are all dirty
- all valid blocks are removed in seg#1
- gc select this sec and next_victim_seg=seg#0
- migrate seg#0, next_victim_seg=seg#1
- checkpoint -> sec(seg#0, seg#1)  becomes free
- allocator assigns sec(seg#0, seg#1) to curseg
- gc tries to migrate seg#1
