[Qemu-devel] [PATCH v7 02/24] blockjob: Call bdrv_unref() on creation error

[Max Reitz <mreitz@redhat.com>]

If block_job_create() fails, it should release its reference to the
job's BDS. Normally, this is done in the callback provided by the
caller, but that callback will not be invoked if the block job failed to
be created.
