ipv4: icmp: convert to dev_net_rcu()
[ Upstream commit 4b8474a0951e605d2a27a2c483da4eb4b8c63760 ]
__icmp_send() must ensure rcu_read_lock() is held, as spotted
by Jakub.
Other ICMP uses of dev_net() seem safe, change them to dev_net_rcu()
to get LOCKDEP support.
Fixes: dde1bc0e6f86 ("[NETNS]: Add namespace for ICMP replying code.")
