Chao Yu c782e68519 f2fs: fix to do sanity check in is_alive() 
commit 77900c45ee5cd5da63bd4d818a41dbdf367e81cd upstream.

In fuzzed image, SSA table may indicate that a data block belongs to
invalid node, which node ID is out-of-range (0, 1, 2 or max_nid), in
order to avoid migrating inconsistent data in such corrupted image,
let's do sanity check anyway before data block migration.
