[PATCH] qapi/block: fix nbd-server-add spec

[Vladimir Sementsov-Ogievskiy]

"NAME" here may be interpreted like it should match @name, which is
export name. But it was never mentioned in such way. Make it obvious,
that actual "<dirty-bitmap-export-name>" (see docs/interop/nbd.txt)
will match @bitmap parameter.
