Now that we can use -EPROBE_DEFER, it's no longer required to spin off
the snd_hdac_i915_init into a workqueue. It's likely the whole workqueue
can be destroyed, but I don't have the means to test this.

Removing the workqueue would simplify init even further, but is left
as exercise for the reviewer.

Nitpick: Half of the commit message is redundant. From the reader/maintainer point of view, presented opinions and suggestions are fine as a part of cover-letter but not in the long run from git log level.

Nitpick: commit title is not a sentence, should not end with full stop.

The 'else' part seems redundant. s/else if/else/.

As I'm aware that this is v6 already, my team can also clean this up later with separate series to not delay the merge any longer.
