5ac8fb035e surjectionproof: make sure that n_used_pubkeys > 0 in generate 
If the proof was generated with surjectionproof_initialize (as mandated by the
API docs), then n_used_pubkeys can never be 0. Without this commit, compilers
will (rightfully) warn that borromean_s[ring_input_index] is not initialized in
surjectionproof_generate. Therefore, this commit makes sure that n_used_pubkeys
is greater than 0 which ensures that the array is initialized at
ring_input_index.

bf18ff5a8c surjectionproof: fix generation to fail when any input == the output 
Verification will fail in this case, so don't "succeed" in generating a bad proof.
