Log Message:
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.
