ctdb-tools: Fix sort order of "ctdb ip" output

ctdb-tools: Fix sort order of "ctdb ip" output

The new hash-table-based method of merging the IP information does not
sort, whereas the RB-tree method implicitly sorted.  This probably
only really matters for the "all" case, but sort regardless to ensure
consistent output format.

Sorting has to be done here instead of when printing to ensure
consistency between ip[] and ipinfo[].

No longer reverse the sort order.
