block: add proper state guards to __elv_next_request
commit 0a58e077eb600d1efd7e54ad9926a75a39d7f8ae upstream.
blk_cleanup_queue() calls elevator_exit() and after this, we can't
touch the elevator without oopsing. __elv_next_request() must check
for this state because in the refcounted queue model, we can still
call it after blk_cleanup_queue() has been called.
This was reported as causing an oops attributable to scsi.
