nbtree VACUUM: Cope with buggy opclasses.

Teach nbtree VACUUM to press on with vacuuming in the event of a page
deletion attempt that fails to "re-find" a downlink for its child/target
page.

There is no good reason to treat this as an irrecoverable error.  But
there is a good reason not to: pressing on at this point removes any
question of VACUUM not making progress solely due to misbehavior from
user-defined operator class code.
