[PATCH] EDAC, sb_edac: Remove VLA usage

[Gustavo A. R. Silva]

In preparation to enabling -Wvla, remove VLA and replace it
with a fixed-length array instead.

Fixed as part of the directive to remove all VLAs from
the kernel: https://lkml.org/lkml/2018/3/7/621

Notice that due to this change, the field max_interleave is no longer
used after it has been initialized. Maybe it should be removed?

Thanks
