Sherry Sun 3ba7550231 mxm_wifiex: fix P2P test fail on kernel higher than L5.12 
P2P test will fail(deadlock) on kernel higher than L5.12,
error log like below:
root@imx8mmevk:~# wpa_cli -i p2p0 p2p_group_add freq=2412
[   47.284346] Add virtual interface p2p-p2p0-0
'P2P_GROUP_ADD freq=2412' command timed out.

This is because the upgarded kernel change the netdevs
registration/unregistration semantics, new kernel require the drivers
to call cfg80211_(un)register_netdevice() when this is happening due to
a cfg80211 request.

For more details, please refer to the upstream patch:
https://lore.kernel.org/linux-wireless/20210122161942.cf2f4b65e4e9.Ida8234e50da13eb675b557bac52a713ad4eddf71@changeid/
