[CRIU] [PATCH v8 11/15] zdtm/net/ipv6: allow inacurate match for mldvX_unsolicited_report_interval

[Pavel Tikhomirov]

mldv1_unsolicited_report_interval and mldv2_unsolicited_report_interval
are rounded up to (MSEC_PER_SEC / HZ)*k when set as in kernel they are
saved in jiffies. As min HZ is 100, 10 is MAX_MSEC_GRANULARITY.
