iwlwifi: mvm: BT Coex fix another NULL pointer dereference
This patch is very similar to a previous fix: 22cba0c0852f When we disassociate, mac80211 removes the station and then, it sets the bss it unsets the assoc bool in bss_info. Since the firwmware wants it the opposite (first set the MAC context as unassoc, and only then, remove the STA of the API), we have a small period of time in which the STA in firmware doesn't have a valid ieee80211_sta pointer. During that time, iwl_mvm_vif->ap_sta_id, is still set to the STA in firmware that represent the AP. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
