Oleg Nesterov 0a0836a09c cfq_get_queue: fix possible NULL pointer access ...

cfq_get_queue()->cfq_find_alloc_queue() can fail, check the returned value.

Note that this isn't a bug at the moment, since the regular IO path
does not call this path without __GFP_WAIT set. However, it could be a
future bug, so I've applied it.
