ALSA: hda - Fix Center/LFE mixer element creations for Realtek

The commit 23c09b00900c3fa6672148738cad29d6fc6ded7c
    ALSA: hda - Support multiple speakers by Realtek auto-parser
changes the return value from alc_get_line_out_pfx(), and it breaks
the center/LFE mixer split check.  The caller must test with a string
"CLFE" now.
