[PATCH 04/10] EDAC/igen6: Fix channel address decode for non-hash mode

[Qiuxu Zhuo]

In non-hash mode, decode_channel_addr() and channel index extraction
used a hardcoded interleave bit position 6 instead of the actual
intlv_bit parameter, causing incorrect channel address decoding.

Fix this by using intlv_bit consistently in both hash and non-hash modes.
