Maulik Shah 31f5f41bff ANDROID: cpuidle-psci: Fix suspicious RCU usage 
This change fixes suspicious RCU usage warnings from vendor hook.

    =============================
    WARNING: suspicious RCU usage
    5.15.41-debug-gc1163f69ba3b-dirty #1 Not tainted
    -----------------------------
    include/trace/events/lock.h:37 suspicious rcu_dereference_check() usage!

    other info that might help us debug this:

    rcu_scheduler_active = 2, debug_locks = 1
    RCU used illegally from extended quiescent state!
    no locks held by swapper/0/0.

    stack backtrace:
    CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.15.41-debug-gc1163f69ba3b-dirty #1
