On a 'qemu-discuss' thread[1], Kevin identifies that the current doc
blurb for @blockdev-add is stale:
This is actually a documentation bug. @id doesn't exist,
blockdev-add never creates a BlockBackend. This was different in the
very first versions of the patches to add blockdev-add and we
probably just forgot to update the documentation after removing it.
So remove the stale bits.
And the requirement for 'node-name' is already mentioned in the
documentation of @BlockdevOptions:
[...]
# @node-name: the node name of the new node (Since 2.0).
# This option is required on the top level of blockdev-add.
# Valid node names start with an alphabetic character and may
# contain only alphanumeric characters, '-', '.' and '_'. Their
# maximum length is 31 characters.
[...]

This would be our first use of this unusual tag name; more typical is
Suggested-by or Reported-by.
Is it worth a 'Fixes: be4b67bc7d' line?

As a doc fix, it is safe for 5.1, but given the timing of -rc2 today,
it's also okay if it slips into 5.2.
