The bounds check on "index" doesn't catch negative values. Using
ARRAY_SIZE() directly is more readable and more robust because it prevents

The WWAN core not only multiplex the netdev configuration data, but
process it too, and needs some space to store its private data
associated with the netdev. Add a structure to keep common WWAN core
data. The structure will be stored inside the netdev private data before
WWAN driver private data and have a field to make it easier to access
the driver data. Also add a helper function that simplifies drivers
access to their data.
At the moment we use the common WWAN private data to store the WWAN data
link (channel) id at the time the link is created, and report it back to
user using the .fill_info() RTNL callback. This should help the user to
be aware which network interface is bound to which WWAN device data
channel.

Most, if not each WWAN device driver will create a netdev for the
default data channel. Therefore, add an option for the WWAN netdev ops
registration function to create a default netdev for the WWAN device.
A WWAN device driver should pass a default data channel link id to the
ops registering function to request the creation of a default netdev, or
a special value WWAN_NO_DEFAULT_LINK to inform the WWAN core that the
default netdev should not be created.
For now, only wwan_hwsim utilize the default link creation option. Other
drivers will be reworked next.

Since the last commit, the WWAN core will remove all our network

Therefore, we can safely drop the custom code that cleans the list of

netdevs were removed earlier in the wwan_unregister_ops() call.
