drm/tests: hdmi: Fix WW_MUTEX_SLOWPATH failures
The light_up_connector helper function in the HDMI infrastructure unit
tests uses drm_atomic_set_crtc_for_connector(), but fails when it
returns an error.

This function can return EDEADLK though if the sequence needs to be
restarted, and WW_MUTEX_SLOWPATH is meant to test that we handle it
properly.

Let's handle EDEADLK and restart the sequence in our tests as well.

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.
