Ajay Singh 12cfc9c8d3 wifi: wilc1000: fix multi-vif management when deleting a vif
Adding then removing a second vif currently makes the first vif not working
anymore. This is visible for example when we have a first interface
connected to some access point:
- create a wpa_supplicant.conf with some AP credentials
- wpa_supplicant -Dnl80211 -c /etc/wpa_supplicant.conf -i wlan0
- dhclient wlan0
- iw phy phy0 interface add wlan1 type managed
- iw dev wlan1 del
wlan0 does not manage properly traffic anymore (eg: ping not working)

This is due to vif mode being incorrectly reconfigured with some default
values in del_virtual_intf, affecting by default first vif.

Prevent first vif from being affected on second vif removal by removing vif
mode change command in del_virtual_intf
