[Analysis]
RCU warning is happened at rcu_dereference -> rcu_dereference_check, rcu_read_lock_held() is a condition check in it.
When rcu_read_lock_held() return false, warning will be printed.

[Fix]
When call ieee80211_bss_get_ie(), the code and related ie need be wrapped around by rcu_read_lock()/rcu_read_unlock().
