[ Upstream commit 54c4664e48eea52f2b296c73ddb8f5629b958678 ]
Commit 0ef2d5afb12d ("i40e: KISS the client interface") simplified the client interface so in practice it supports only one client per i40e netdev. But we have still 2 notification functions that uses as parameter a pointer to VSI of netdevice associated with the client. After the mentioned commit only possible and used VSI is the main (LAN) VSI. So refactor these functions so they are called with PF pointer argument and the associated VSI (LAN) is taken inside them.
