i40e: Cleanup PTP registration on probe failure

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.

Both of these conditions have been present since PTP was introduced in
this driver.

Found with coccinelle.
