afs: Fix error handling in VL server rotation
The error handling in the VL server rotation in the case of there being no contactable servers is not correct. In such a case, the records of all the servers in the list are scanned and the errors and abort codes are mapped and prioritised and one error is chosen. This is then forgotten and the default error is used (EDESTADDRREQ). Fix this by using the calculated error. Also we need to note whether a server responded on one of its endpoints so that we can priorise an error from an abort message over local and network errors.

A DT changeset is a method which allows one to apply changes
in the live tree in such a way that either the full set of changes
will be applied, or none of them will be. If an error occurs partway
through applying the changeset, then the tree will be rolled back to the
previous state. A changeset can also be removed after it has been
applied.

When a changeset is applied, all of the changes get applied to the tree
at once before emitting OF_RECONFIG notifiers. This is so that the
receiver sees a complete and consistent state of the tree when it
receives the notifier.

The sequence of a changeset is as follows.

1. of_changeset_init() - initializes a changeset

2. A number of DT tree change calls, of_changeset_attach_node(),
of_changeset_detach_node(), of_changeset_add_property(),
of_changeset_remove_property, of_changeset_update_property() to prepare
a set of changes. No changes to the active tree are made at this point.
All the change operations are recorded in the of_changeset 'entries'
list.

3. of_changeset_apply() - Apply the changes to the tree. Either the
entire changeset will get applied, or if there is an error the tree will
be restored to the previous state. The core ensures proper serialization
through locking. An unlocked version __of_changeset_apply is available,
if needed.

If a successfully applied changeset needs to be removed, it can be done
with of_changeset_revert().
