IB/core: Fix possible crash to access NULL netdev
[ Upstream commit bb7f8f199c354c4cf155b1d6d55f86eaaed7fa5a ]
resolved_dev returned might be NULL as ifindex is transient number.
Ignoring NULL check of resolved_dev might crash the kernel.
Therefore perform NULL check before accessing resolved_dev.
Additionally rdma_resolve_ip_route() invokes addr_resolve() which
performs check and address translation for loopback ifindex.
Therefore, checking it again in rdma_resolve_ip_route() is not helpful.
Therefore, the code is simplified to avoid IFF_LOOPBACK check.
Fixes: 200298326b27 ("IB/core: Validate route when we init ah")
