[PATCH v2 2/6] block: move disk announce work from register_disk() to a helper

Luis Chamberlain

This moves quite a bit of code which does one thing into a helper.
We currently do not check for errors but we may decide that might
be desirable later.

This also makes the code easier to read.

This change has no functional changes.
