net: ipv6: Fix ipv6_recv_error signature

When the ipv6 ping code was backported the code appears to have been
cherry picked from upstream without adjusting the signature of
ipv6_recv_error(). In upstream and in the cherry pick the final addr_len
parameter has been dropped but the v3.10 definition had this argument.
Adjust the definition and all callers to follow the upstream pattern.
