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.
