[PATCH v2 05/17] Do not check the same head_pos twice

From: Michael Haggerty <mhagger@alum.mit.edu>

Once a match has been found at head_pos, the entry is zeroed and no future attempts will match that entry. So increment head_pos to avoid checking against the zeroed-out entry during the next iteration.
