    Fix recent memory leak in locate_kdc.c
    
    Commit ce112dec844e4650b5ad174bd40f21c32aebe1d1 introduced a memory
    leak in locate_srv_conf_1() by moving the free(realmstr) call to the
    cleanup handler, because there was an early return after realmstr is
    allocated.  Convert that early return to a goto.
