Ajay Singh b66b008f1d wifi: wilc1000: fix multi-vif management when deleting a vif
[ Upstream commit 12cfc9c8d3faf887a202c89bc312202445fca7e8 ]

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

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
