[PATCH] ptp: fix PTP PPS source's lookup cookie set

The setting took place before the PTP PPS source was registered, so
ptp->pps_source was NULL.

Fixes: 8602e40fc813 ("ptp: Set lookup cookie when creating a PTP PPS source.")

this pastch does not apply to the current net tree, that is why I keep marking it "Not Applicable"
in patchwork.

I applied and tested the patch this morning on the mainline kernel. What am I missing?
Should I wait for the merge windows to end?

Thanks and regards,
Dario

I'll send a patch against -net in a minue.  The earlier ones
were against -net-next, I didn't realize the window closed.
