MLK-19517-07 brcmfmac: remove "arp_hostip_clear" from "brcmf_netdev_stop"
The firmware does not respond ARP request and causes ping failed with
following steps.
1. Bring up inteface
ifconfig wlan0 up or start wpa_supplicant
2. Set the IP address
ifconfig wlan0 192.168.100.10
3. Bring down interface or
ifconfig wlan0 down or kill wpa_supplicant
4. Bring up inteface again and set the same IP address
5. Connect to AP(192.168.100.1) and ping to AP will be failed.
FMAC clears arp_hostip when bringing down the interface, but not set it
back if setting the same IP address. We are able to see the IP address
in interface info(inconfig wlan0) but the ping still cannot work because
the firmware ARP offload does not respond the ARP request.
Because of that, we remove "arp_hostip_clear" from function
"brcmf_netdev_stop"
