defrag.f2fs: fix missing SSA updates
defrag.f2fs: fix missing SSA updates

Previously SSA is updated if it is not included in current segment info.
But, defrag.f2fs doesn't handle current segment info during the process, and
instead lastly update the whole current segment info at a time.
So, we need to update summary entries all the time.
Otherwise, we can lose the SSA entry.
