    Fix a breakout of loops

    As the comment "find first available ipv4 address" indicates,
    if an IP address is found, we need to leave the two nested loops,
    a loop for an interface list and a loop for IP addresses of
    an interface. However, the original code broke away only from
    the inner loop.

    The original (wrong) behavior was non-critical, which just
    returned a non-first IP address. Unfortunately, after applying
    psref, the behavior may call psref_acquire twice to a target
    with the same psref object, resulting in a kernel panic eventually.
