[PATCH v2 0/6] block: add error handling for *add_disk*()

This v2 has the following changes:

- rebases onto a fresh linux-next which includes Christoph's
latest cleanups
- dropping error injection as I inspect ebpf and other
alternatives, yet I still tested this series with that
patch and the only change needed was the last one.
- adds a new patch, the last one, to adjust to our
preference now to always wish for users to call a cleanup
like blk_cleanup_disk() when add_disk() fails.
- dropped driver conversion

Although I've dropped driver conversion at this point I've
converted all drivers over, but that series is about 80
patches... and so should be dealt with after this basic core
work is reviewed and merged.

Luis Chamberlain (6):
block: refcount the request_queue early in __device_add_disk()
block: move disk announce work from register_disk() to a helper
block: move disk invalidation from del_gendisk() into a helper
block: move disk unregistration work from del_gendisk() to a helper
block: add initial error handling for *add_disk()* and friends
block: skip queue if NULL on blk_cleanup_queue()
