amd64_edac:__amd64_set_scrub_rate(): avoid overindexing scrubrates[]
commit 168bfeef7bba3f9784f7540b053e4ac72b769ce9 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.
