null_blk: describe the usage of fault injection param

As null_blk is a very good start point to test block layer, this patch
adds description and comments to 'timeout', 'requeue' and 'init_hctx' to
explain how to use fault injection with null_blk.

The nvme has similar with nvme_core.fail_request in the form of comment.
