bpf, devmap: Pass lockdep expression to RCU lists
...
commit 485ec2ea9cf556e9c120e07961b7b459d776a115 upstream.
head is traversed using hlist_for_each_entry_rcu outside an RCU
read-side critical section but under the protection of dtab->index_lock.
Hence, add corresponding lockdep expression to silence false-positive
lockdep warnings, and harden RCU lists.
Fixes: 6f9d451ab1 ("xdp: Add devmap_hash map type for looking up devices by hashed index")
