IPv4: Fix incorrect expert info for IGMP TTL
IGMP uses TTL = 1 for the network control block. The code assumes
a certain registered multicast destination address always carries
traffic for that protocol, which isn't true. For example mDNS
usually uses a TTL of 255 but IGMP Membership reports use a TTL
of 1 for the same destination address.
The end result is that IGMP traffic to mDNS multicast destination
shows a confusing and incorrect "TTL != 255 for the Local Network
Control Block" expert info.
Rename the "ttl" variable for clarity.
