net: igmp: Don't flush routing cache when force_igmp_version is modified
The procfs knob /proc/sys/net/ipv4/conf/*/force_igmp_version allows the IGMP protocol version to use to be explicitly set. As a side effect this caused the routing cache to be flushed as it was declared as a DEVINET_SYSCTL_FLUSHING_ENTRY. Flushing is unnecessary and this patch makes it so flushing does not occur. Requested by Hannes Frederic Sowa as he was reviewing other patches adding procfs entries.
