[ Upstream commit f7c125bd79f50ec6094761090be81d02726ec6f4 ]
MHI driver registers network device without setting the
needs_free_netdev flag, and does NOT call free_netdev() when
unregisters network device, which causes a memory leak.
This patch calls free_netdev() to fix it since netdev_priv
is used after unregister.
Fixes: 13adac032982 ("net: mhi_net: Register wwan_ops for link creation")
