ipv6: mcast: fix unsolicited report interval after receiving querys
[ Upstream commit 6c6da92808442908287fae8ebb0ca041a52469f4 ] After recieving MLD querys, we update idev->mc_maxdelay with max_delay from query header. This make the later unsolicited reports have the same interval with mc_maxdelay, which means we may send unsolicited reports with long interval time instead of default configured interval time. Also as we will not call ipv6_mc_reset() after device up. This issue will be there even after leave the group and join other groups.
