f2fs: fix to fetch ino via ino_of_node() under cache lock

In f2fs_writeback_node_caches(), it's better to fetch ino via ino_of_node()
under cache lock, otherwise, node cache content may become stale after cache
is unlocked due to racing w/ truncation.

Commit 493b9dc8b52c ("f2fs: cache: use node cache") fixes similar issue in
f2fs_flush_inline_data() introduced in commit 34c061ad85a2 ("f2fs: Avoid double
lock for cp_rwsem during checkpoint").
