Subject: [PATCH AUTOSEL 6.2 19/53] ice: add missing checks for PF vsi type

From: Jesse Brandeburg <jesse.brandeburg@...el.com>

[ Upstream commit 6a8d013e904ad9a66706fcc926ec9993bed7d190 ]

There were a few places we had missed checking the VSI type to make sure
it was definitely a PF VSI, before calling setup functions intended only
for the PF VSI.

This doesn't fix any explicit bugs but cleans up the code in a few
places and removes one explicit != vsi->type check that can be
superseded by this code (it's a super set)
