block: fix aio_flush segfaults for read-only protocols (e.g. curl)
Not all block format drivers expose an io_flush method (reasonable for read-only protocols), so calling io_flush there will immediately segfault. Fix by checking for the method's existence before calling it. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
