If 'devm_init_badblocks()' fails, a previous 'blk_alloc_disk()' call must
be undone.

This patch is speculative. Several fixes on error handling paths have been
done recently, but this one has been left as-is. There was maybe a good
reason that I have missed for that. So review with care!
I've not been able to identify a Fixes tag that please me :(
