ALSA: x86: fix error return code in hdmi_lpe_audio_probe()

platform_get_irq() returns an error code, but the intel_hdmi_audio
driver ignores it and always returns -ENODEV. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly. Also,
notice that platform_get_irq() no longer returns 0 on error.

Print error message and propagate the return value of platform_get_irq
on failure.
