qmi_wwan: avoid RCU stalls on device disconnect when in QMAP mode
[ Upstream commit a8fdde1cb830e560208af42b6c10750137f53eb3 ]
Switch qmimux_unregister_device() and qmi_wwan_disconnect() to
use unregister_netdevice_queue() and unregister_netdevice_many()
instead of unregister_netdevice(). This avoids RCU stalls which
have been observed on device disconnect in certain setups otherwise.
