EDAC/igen6: Fix channel selection hash

In channel selection hash mode, the hardware decoding logic always
includes the channel interleave bit in XOR operations. However, the
hash mask may or may not include this channel interleave bit. When
the mask does include this bit, the current igen6_edac code performs
XOR on the interleave bit twice, effectively ignoring it - which is
incorrect.

Fix this issue by ensuring the hash mask always includes the interleave
bit, so XOR is performed on the interleave bit exactly once.
