[PATCH] ALSA: hda: fix kstrdup return value

[Heloise NH <kernelpatch_update@163.com>]

From: kernelpatch_update <kernelpatch_update@163.com>

In kstrdup we should return -ENOMEM when it reports an 
memory allocation failure, while the -ENODEV is referred
to a failure in finding the cpu node in the device tree.
