ALSA: intel_hdmi: Use strlcpy() instead of strncpy()

Browse Source 
commit c288248f5b26cd5563112fcdc077bf44964a942d upstream.

hdmi_lpe_audio_probe() copies the pcm name string via strncpy(), but
as a gcc8 warning suggests, it misses a NUL terminator, and unlikely
the expected result.

Use the proper one, strlcpy() instead.
