Merge branch 'net-fib-fix-two-use-after-free-in-drivers-during-rcu-dump'

Kuniyuki Iwashima says:

====================
net: fib: Fix two use-after-free in drivers during RCU dump.

syzbot reported fib_info UAF in netdevsim, and the same bug
exists in rocker and mlxsw.

Patch 1 fixes it, and Patch 2 fixes the same type of bug of
fib_rule.
