[PATCH] ALSA: hda/realtek: fix flexible_array.cocci warning

[Guo Zhengkui]

Fix following coccicheck warnings:
./sound/pci/hda/patch_realtek.c:128:4-24: WARNING use
flexible-array member instead.

There is a regular need in the kernel to provide a way
to declare having a dynamically sized set of trailing
elements in a structure. Kernel code should always use
“flexible array members” for these cases. The older style
of one-element or zero-length arrays should no longer be used.
