At __inode_add_ref(), we treating any error returned from btrfs_lookup_dir_item() or from btrfs_lookup_dir_index_item() as meaning that there is no existing directory entry in the fs/subvolume tree. This is not correct since we can get errors such as, for example, -EIO when reading extent buffers while searching the fs/subvolume's btree. So fix that and return the error to the caller when it is not -ENOENT.

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.
