BUG 9139: Fix the username map optimization.
If we successfully map a user. We call
set_last_from_to(user_in, unixname);
in the while loop reading the map file. After a successfull map we don't
stop and continue the loop to check all other mappings in the username
mapfile. But when we hit the end of the file and leave the loop we call:
set_last_from_to(user_in, user_in);
This overwrites the successful mapping, and the next time we call
map_username() we skip the username and no mapping is done.
