Eric Biggers f5ec592dd3 block: simplify calling convention of elv_unregister_queue() 
Make elv_unregister_queue() a no-op if q->elevator is NULL or is not
registered.

This simplifies the existing callers, as well as the future caller in
the error path of blk_register_queue().

Also don't bother checking whether q is NULL, since it never is.
