BUG/MINOR: spoe: do not assume agent->rt is valid on exit

Browse Source 
As reported by Christopher, we may call spoe_release_agent() when leaving
after an allocation failure or a config parse error. We must not assume
agent->rt is valid there as the allocation could have failed.

This should be backported to 1.9 and 1.8.
