amd64_edac: Fix interleaving check
commit e726f3c368e7c1919a7166ec09c5705759f1a69d upstream.
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.
