Subject: [PATCH net-next 1/3] ipv6: mld: rename mc_maxdelay into mc_uri

The name mc_maxdelay is quite confusing as it actually denotes the
unsolicited report interval. Since we have query response interval
named as mc_qri, name unsolicited report interval analogously as
mc_uri. Note that both are not the same!
