[PATCH] net: bluetooth: hci_core: Use list_for_each_entry_rcu() to traverse RCU list in RCU read-side CS

[madhuparnabhowmik10]

From: Madhuparna Bhowmik <madhuparnabhowmik10@xxxxxxxxx>

In function hci_is_blocked_key() RCU list is traversed with
list_for_each_entry() in RCU read-side CS.
Use list_for_each_entry_rcu() instead.
