Export the bp_usbnet_get_stats64() function only on kernel < 4.11,
because this function is only available on such kernel versions.

On kernel > 4.11.9 the new member priv_destructor should be set in
netdev_set_priv_destructor() and not the old destructor member any more,
it was removed.
This fixes the build on >= 4.11.9.

This function was added in kernel 3.18 in commit 068765ba7987e ("PM /
sleep: Mechanism for aborting system suspends unconditionally") In our
implementation we only call pm_system_wakeup(() and do not handle the
abortion of the current suspend process.

freeze_wake() was also "only" added around 3.10 or something like that,
so perhaps we should just not backport this at all but version-guard
the drivers needing it? I'm not super comfortable with the reduced
functionality anyway.

Hi,
This is only used by mwifiex so I am also fine with making mwifiex
depend on kernel 3.18 or higher.
Will you create a patch and revert mine?
