[RFC v1 0/6] block: add error handling for *add_disk*()

From: Luis Chamberlain

While working on some blktrace races I noticed that we don't do
error handling on *add_disk*() and friends. This is my initial
work on that.

This is based on linux-next tag next-20200428, you can also get this
on my branch 20200428-block-fixes [0].

Let me know what you think.
