Amol Grover ab48c14a44 bpf, devmap: Pass lockdep expression to RCU lists ...

commit 485ec2ea9c 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.
