Jaegeuk Kim 87a597c7a7 f2fs: relax node version check for victim data in gc 
[ Upstream commit c13ff37e359bb3eacf4e1760dcea8d9760aa7459 ]

- has_not_enough_free_secs
node_secs: 0  dent_secs: 0  freed:0  free_segments:103  reserved:104

          - f2fs_gc
             - get_victim_by_default
alloc_mode 0, gc_mode 1, max_search 2672, offset 4654, ofs_unit 1

                - do_garbage_collect
start_segno 3976, end_segno 3977   type 0

                  - is_alive
nid 22797, blkaddr 2131882, ofs_in_node 0, version 0x8/0x0

                   - gc_data_segment 766, segno 3976, block 512/426 not alive

So, this patch fixes subtle corrupted case where node version does not match
to summary version which results in infinite loop by gc.
