Policy - Foreground GC, LFS and greedy GC mode. Under this policy, f2fs_gc() loops forever to GC as it doesn't have enough free segements to proceed and thus it keeps calling gc_more for the same victim segment. This can happen if the selected victim segment could not be GC'd due to failed blkaddr validity check i.e. is_alive() returns false for the blocks set in current validity map. Fix this by keeping track of such invalid segments and skip those segments for selection in get_victim_by_default() to avoid endless GC loop under such error scenarios. Currently, add this logic under CONFIG_F2FS_CHECK_FS to be able to root cause the issue in debug version.
