net: kill an RCU warning in inet_fill_link_af()

commits 9f0f7272 (ipv4: AF_INET link address family) and cf7afbfeb8c
(rtnl: make link af-specific updates atomic) used incorrect
__in_dev_get_rcu() in RTNL protected contexts, triggering PROVE_RCU
warnings.

Switch to __in_dev_get_rtnl(), wich is more appropriate, since we hold
RTNL.

Based on a report and initial patch from Amerigo Wang.
