[PATCH] (9/9) freenetdev - fix leaky drivers

[Stephen Hemminger <shemminger@xxxxxxxx>]

When doing the audit for this change, it was obvious that several drivers
allocate but never free the net_device.

This fixes these drivers.  This patch is riskier than the earlier
ones, because it isn't just a simple substitution and maybe there
is a reason they never free.
