[PATCH 1/2] pci: Convert to use built-in RCU list checking

[Joel Fernandes (Google)]

CONFIG_PROVE_RCU_LIST requires list_for_each_entry_rcu() to pass a
lockdep expression if using srcu or locking for protection. It can only
check regular RCU protection, all other protection needs to be passed as
lockdep expression.
