[Intel-wired-lan] [PATCH net] i40e: Cleanup PTP upon probe failure

[Matt Vollrath <tactii@gmail.com>]

Fix two conditions which would leak PTP registration on probe failure:

1. i40e_setup_pf_switch can encounter an error in
    i40e_setup_pf_filter_control, call i40e_ptp_init, then return
    non-zero, sending i40e_probe to err_vsis.

2. i40e_setup_misc_vector can return non-zero, sending i40e_probe to
    err_vsis.

Found with coccinelle.
