Paolo Abeni 8e0e47f038 ipmr: fix tables suspicious RCU usage 
[ Upstream commit fc9c273d6d ]

Similar to the previous patch, plumb the RCU lock inside
the ipmr_get_table(), provided a lockless variant and apply
the latter in the few spots were the lock is already held.

Fixes: 709b46e8d9 ("net: Add compat ioctl support for the ipv4 multicast ioctl SIOCGETSGCNT")
Fixes: f0ad0860d0 ("ipv4: ipmr: support multiple tables")
