[ Upstream commit 9199b915e9fad7f5eff6160d24ff6b38e970107d ]
In cited commit, netdev_tracker_alloc() is called for the newly
allocated xfrm state, but dev_hold() is missed, which causes netdev
reference count imbalance, because netdev_put() is called when the
state is freed in xfrm_dev_state_free(). Fix the issue by replacing
netdev_tracker_alloc() with netdev_hold().

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.
