f2fs: fix to unlock page correctly in error path of is_alive()

Browse source

As Pavel Machek reported in below link [1]:

After commit 77900c45ee ("f2fs: fix to do sanity check in is_alive()"),
node page should be unlock via calling f2fs_put_page() in the error path
of is_alive(), otherwise, f2fs may hang when it tries to lock the node
page, fix it.
