Murad Masimov c9bd4a82b4 ALSA: hda/cs8409: Fix possible NULL dereference 
If snd_hda_gen_add_kctl fails to allocate memory and returns NULL, then
NULL pointer dereference will occur in the next line.

Since dolphin_fixups function is a hda_fixup function which is not supposed
to return any errors, add simple check before dereference, ignore the fail.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 20e5077241 ("ALSA: hda/cs8409: Add support for dolphin")
