ALSA: hda - Fix invalid function call in snd_hda_add_vmaster()
The recent commit [6194b99d: ALSA: hda - Kill the rest of snd_print*()
usages] changed the callback map_slaves(), but one call was forgotten
to be replaced due to the cast, which leads to kernel Oops due to
invalid function. This patch replaces it with a proper function.
Fixes: 6194b99de9f5 ('ALSA: hda - Kill the rest of snd_print*() usages')
