crush: ensure bucket id is valid before indexing buckets array
We were indexing the buckets array without verifying the index was
within the [0,max_buckets) range. This could happen because
a multistep rule does not have enough buckets and has CRUSH_ITEM_NONE
for an intermediate result, which would feed in CRUSH_ITEM_NONE and
make us crash.
Reflects ceph.git commit 976a24a326da8931e689ee22fce35feab5b67b76.
