At btrfs_orphan_cleanup(), if we were able to find the inode, we do an
iput() on the inode, then if btrfs_drop_verity_items() succeeds and then
either btrfs_start_transaction() or btrfs_del_orphan_item() fail, we do
another iput() in the respective error paths, resulting in an extra iput()
on the inode.
Fix this by setting inode to NULL after the first iput(), as iput()
ignores a NULL inode pointer argument.
Fixes: a13bb2c038 ("btrfs: add missing iputs on orphan cleanup failure")

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 Restructured Text 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.
