Wrapper for lower-level revalidate_disk routines.
This is a wrapper for the lower-level revalidate_disk call-backs such
as sd_revalidate_disk(). It allows us to perform pre and post
operations when calling them.
We will use this wrapper in a later patch to adjust block device sizes
after an online resize (a _post_ operation).
