[v2,1/4] driver core: Make driver_deferred_probe_timeout a static variable

It is not used outside of its compilation unit, so there's no need to
export this variable.

Could you please pick this patch? Is a fix independent of the other
patches in the series and it has already been acked by John.

It is the middle of the merge window and I can't take anything now until
after 6.2-rc1 is out.  I also really can't take individual patches out
of a patch series easily, so please just resend it as a single patch
when 6.2-rc1 is out.

thanks,
