phylink has historically not permitted a PCS to be removed. An attempt to permit this with phylink_set_pcs() resulted in comments indicating that there was no need for this. This behaviour has been propagated forward to the mac_select_pcs() approach as it was believed from these comments that changing this would be NAK'd. However, with mac_select_pcs(), it takes more code and thus complexity to maintain this behaviour, which can - and in this case has - resulted in a bug. If mac_select_pcs() returns NULL for a particular interface type, but there is already a PCS in-use, then we skip the pcs_validate() method, but continue using the old PCS. Also, it wouldn't be expected behaviour by implementers of mac_select_pcs(). Allow this by removing this old unnecessary restriction.
