If a setxattr operation finds an xattr structure in leaf format, adding the attr can fail due to lack of space and hence requires an upgrade to node format. After this happens, we'll roll the transaction and re-enter the state machine, at which time we need to perform a second lookup of the attribute name to find its new location. This lookup attaches a new da state structure to the xfs_attr_item but doesn't free the old one (from the leaf lookup) and leaks it. Fix that. Signed-off-by: Darrick J.

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.
