block: Fix NULL dereference on empty drive error
blk_error_action() sends a BLOCK_IO_ERROR QMP event which includes the node name of its root node. If the BlockBackend represents an empty drive, there is no root node, so we should not try to access its node name. Make the field optional in the event and include it only when the BlockBackend isn't empty. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
