In our rename process, region of f2fs_lock_op covered is too big as some of the
code like f2fs_empty_dir/f2fs_find_entry are not needed to protect by this lock.
So in the extreme case like doing checkpoint when we rename old inode to exist
inode in a large directory could cause lower concurrency.
This patch correct releasing code of new_page to avoid BUG_ON in error patch of
f2fs_rename.

Although building NAT journal in cursum reduce the read/write work for NAT

frequently for these cases:
1. if journal in cursum has already full, it's a bit of waste that we flush all
nat entries to page for persistence,
Hi Chao,
Thank you for the patch. :)
Just one minor suggestion.
