ipv6: Don't pass invalid dst_entry pointer to dst_release().
Make sure dst_release() is not called with error pointer. This is similar to commit 4910ac6c526d2868adcb5893e0c428473de862b5 ("ipv4: Don't ip_rt_put() an error pointer in RAW sockets."). Signed-off-by: Boris Ostrovsky <boris.ostrovsky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
