ALSA: hda: Make device usage_count consistent across subsequent probing

AVS HDAudio bus driver does not tie with codec drivers tighly and
snd_hda_codec_device_new() can be called after codec's module reload. In
such case, rpm is forbidden and invoking pm_runtime_forbid()
unconditionally causes device's usage_count to become unbalanced. This
is later caught by WARN_ON() found in sound/soc/hda.c. Detect such
circumstance and bump the usage_count instead.
