stream: fix crash in stream_start() when block_job_create() fails
The code that tries to reopen a BlockDriverState in stream_start()
when the creation of a new block job fails crashes because it attempts
to dereference a pointer that is known to be NULL.
This is a regression introduced in a170a91fd3eab6155da39e740381867e,
likely because the code was copied from stream_complete().
