block/qapi: Remove redundant NULL check to silence Coverity
When skipping implicit nodes in bdrv_block_device_info(), we know that
bs0 is always non-NULL; initially, because it's taken from a BdrvChild
and a BdrvChild never has a NULL bs, and after the first iteration
because implicit nodes always have a backing file.
Remove the NULL check and add an assertion that the implicit node does
indeed have a backing file.
