net: rtm_to_ifaddr: free ifa if ifa_cacheinfo processing fails
[ Upstream commit 446266b0c742a2c9ee8f0dce759a0117bce58a86 ] Commit 5c766d642 ("ipv4: introduce address lifetime") leaves the ifa resource that was allocated via inet_alloc_ifa() unfreed when returning the function with -EINVAL. Thus, free it first via inet_free_ifa(). Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Reviewed-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
