Revert "block: add callback function for unplug notification"
MD can't use this since it really requires us to be able to
keep more than a single piece of state for the unplug. Commit
048c9374 added the required support for MD, so get rid of this
now unused code.
This reverts commit f75664570d8b75469cc468f23c2b27220984983b.
