block: don't assume device has a request list backing in nr_requests store
commit b8a9ae779f2c7049071034661e09cb7e1e82250c upstream.

we could make the limit apply on stacked devices too, for throttling
reasons.
This fixes
5a54cd13353bb3b88887604e2c980aa01e314309
and should go into 2.6.31 stable as well.
