f2fs: fix to tag gcing flag on page during block migration 



It needs to add missing gcing flag on page during block migration,
in order to garantee migrated data be persisted during checkpoint,
otherwise out-of-order persistency between data and node may cause
data corruption after SPOR.

Similar issue was fixed by commit 2d1fe8a8 ("f2fs: fix to tag
gcing flag on page during file defragment").
