If the following call path returns an error from switchdev:
nbp_vlan_flush
-> __vlan_del
-> __vlan_vid_del
-> br_switchdev_port_vlan_del
-> __vlan_group_free
-> WARN_ON(!list_empty(&vg->vlan_list));
then the deletion of the net_bridge_vlan is silently halted, which will
trigger the WARN_ON from __vlan_group_free().
The WARN_ON is rather unhelpful, because nothing about the source of the
error is printed. Add a print to catch errors from __vlan_del.

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.
