Summary
net: wwan: mhi: fix memory leak in mhi_mbim_dellink
Details

In the Linux kernel, the following vulnerability has been resolved:

net: wwan: mhi: fix memory leak in mhimbimdellink

MHI driver registers network device without setting the needsfreenetdev flag, and does NOT call free_netdev() when unregisters network device, which causes a memory leak.

This patch sets needsfreenetdev to true when registers network device, which makes netdev subsystem call freenetdev() automatically after unregisternetdevice().
