ALSA: intel_hdmi: Fix off-by-one error in __hdmi_lpe_audio_probe()

In __hdmi_lpe_audio_probe(), strscpy() is incorrectly called with the
length of the source string (excluding the NUL terminator) rather than
the size of the destination buffer. This results in one character less
being copied from 'card->shortname' to 'pcm->name'.

Use the destination buffer size instead to ensure the card name is
copied correctly.
