tipc: Fix bug in topology server byte swapping routine
This patch fixes TIPC's topology server so that it does byte swapping
correctly when endianness conversion is required. (Note: This bug only
impacted an application if it issues a subscription request to a
topology server on another node, rather than the server on it's own
node; since the topology server is normally not accessible by off-node
applications, most TIPC applications were not impacted by the bug.)
