C type coercion rules require that negative numbers be converted into positive numbers via wraparound such that a negative -1 becomes a positive 1. This causes vn_getf to return a file handle when it should return NULL whenever a positive file descriptor existed with the same value. We should check for a negative file descriptor and return NULL instead. This was caught by ClusterHQ's unit testing.
