i40e: Cleanup PTP pins on probe failure

Browse source

commit 678b713ece upstream.

PTP pin structs are allocated early in probe, but never cleaned up.

Fix this by calling i40e_ptp_free_pins in the error path.

To support this, i40e_ptp_free_pins is added to the header and
pin_config is correctly nullified after being freed.

This has been an issue since i40e_ptp_alloc_pins was introduced.
