The exception handling path for the __fbnic_pm_resume function had a bug in
that it was taking the devlink lock and then exiting to exception handling
instead of waiting until after it released the lock to do so. In order to
handle that I am swapping the placement of the unlock and the exception
handling jump to label so that we don't trigger a deadlock by holding the
lock longer than we need to.
In addition this change applies the same ordering to the rtnl_lock/unlock
calls in the same function as it should make the code easier to follow if
it adheres to a consistent pattern.

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.
