block: mirror - use local_err to avoid NULL errp
When starting a block job, commit_active_start() relies on whether *errp
is set by mirror_start_job. This allows it to determine if the mirror
job start failed, so that it can clean up any changes to open flags from
the bdrv_reopen(). If errp is NULL, then it will not be able to
determine if mirror_start_job failed or not.
To avoid this, use a local Error variable, and then propagate the error
(if any) to errp.
