wifi: ath11k: adjust unlock sequence in ath11k_update_stats_event()

Currently RCU lock and ar->data_lock are acquired in a sequence of

	rcu_read_lock()
	spin_lock_bh(&ar->data_lock)

but released in a sequence of

	rcu_read_unlock()
	spin_unlock_bh(&ar->data_lock)

Although there are no apparent issues with this, reorder them to
achieve symmetry.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.37
