Subject: i40iw: Do not free sqbuf when event is I40IW_TIMER_TYPE_CLOSE
From: Mustafa Ismail <mustafa.ismail@xxxxxxxxx>
[ Upstream commit 10499986dbd8778e1acf9f9d2e166800dfee44b4 ]
When the event type is I40IW_TIMER_TYPE_CLOSE, there is no sqbuf and
it should not be freed as one in i40iw_schedule_cm_timer().
Fixes: f27b4746f378 ("i40iw: add connection management code")
