[PATCH 0/2] block: do not try to list nearly-dropped filters

[Andrey Zhadchenko via <qemu-devel@nongnu.org>]

QEMU crashes on QMP command 'query-named-block-nodes' if we have
finalized but not dismissed block job with filter, for example
block-stream.
This happens because the filter no longer has references from which
QEMU can query block info. Skip such filters while listing block nodes.

This patchset also adds simple test for this case.

  block: do not try to list nearly-dropped filters
  iotests: add new test case for image streaming
