Eric Dumazet 035320d547 ipmr: dont corrupt lists 
ipmr_rules_exit() and ip6mr_rules_exit() free a list of items, but
forget to properly remove these items from list. List head is not
changed and still points to freed memory.

This can trigger a fault later when icmpv6_sk_exit() is called.

Fix is to either reinit list, or use list_del() to properly remove items
from list before freeing them.

bugzilla report : https://bugzilla.kernel.org/show_bug.cgi?id=16120

Introduced by commit d1db275dd3 (ipv6: ip6mr: support multiple
tables) and commit f0ad0860d0 (ipv4: ipmr: support multiple tables)
