[PATCH 2/6] block: allow REQ_NOWAIT zone management commands

[Christoph Hellwig <hch@lst.de>]

Commit efae226c2ef1 ("block: handle zone management operations
completions") moved all block layer tracking of zone management
operations to the I/O completion handler.  With that REQ_NOWAIT zone
management operations are just fine, so allow them.
