amd64_edac: Fix interleaving check

When matching error address to the range contained by one memory node,
we're in valid range when node interleaving

1. is disabled, or
2. enabled and when the address bits we interleave on match the
interleave selector on this node (see the "Node Interleaving" section in
the BKDG for an enlightening example).

Thus, when we early-exit, we need to reverse the compound logic
statement properly.
