Andrew Morton a322f9a079 amd64_edac:__amd64_set_scrub_rate(): avoid overindexing scrubrates[] 
commit 168bfeef7b upstream.

If none of the elements in scrubrates[] matches, this loop will cause
__amd64_set_scrub_rate() to incorrectly use the n+1th element.

As the function is designed to use the final scrubrates[] element in the
case of no match, we can fix this bug by simply terminating the array
search at the n-1th element.

Boris: this code is fragile anyway, see here why:

It will be rewritten more robustly soonish.
