fix memory leak in protover.c
Fix a memory leak where directory authorities would leak a chunk of
memory for every router descriptor every time they considered voting.
This bug was taking down directory authorities in the live network due
to out-of-memory issues.
Fixes bug 26435; bugfix on 0.3.3.6.
