Mike Krinkin 21974061cf null_blk: fix use-after-free problem ...

end_cmd finishes request associated with nullb_cmd struct, so we
should save pointer to request_queue in a local variable before
calling end_cmd.

The problem was causes general protection fault with slab poisoning
enabled.

Fixes: 8b70f45e2e ("null_blk: restart request processing on completion handler")
