Subject: [PATCH v7 04/13] ASoC: SOF: Intel: Fix error handling in hda_init()

The hda_codec_i915_init() errors are ignored in
hda_init() so it can never return -EPROBE_DEFER.

Fix this before we move the call to hda_init() from the
deferred probe to early probe.

While at it, also fix error handling when hda_dsp_ctrl_get_caps
fails.
