In f2fs_new_inode(), if we fail to get a new inode, we go iput(), followed by
f2fs_evict_inode(). If the inode is not marked as bad, it'll try to call
f2fs_remove_inode_page() which tries to read the inode block given node id.
But, there's no block address allocated yet, which gives a chance to access
a wrong block address, if the block device has some garbage data in NAT table.
We need to make sure NAT table should have zero data for all the unallocated
node ids, but also would be better to take this unnecessary path as well.
Let's mark the faild inode as bad.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
