net: Revert "ipv4: fix a deadlock in ip_ra_control"
This reverts commit 1215e51edad1.
Since raw_close() is used on every RAW socket destruction,
the changes made by 1215e51edad1 scale sadly. This clearly
seen on endless unshare(CLONE_NEWNET) test, and cleanup_net()
kwork spends a lot of time waiting for rtnl_lock() introduced
by this commit.
Previous patch moved IP_ROUTER_ALERT out of rtnl_lock(),
so we revert this patch.
