Subject: [PATCH net-next 03/13] ice: drop unnecessary VF parameter from several VSI functions

From: Jacob Keller <jacob.e.keller@...el.com>

The vsi->vf pointer gets assigned early on during ice_vsi_alloc. Several
functions currently take a VF pointer, but they can just use the existing
vsi->vf pointer as needed. Modify these functions to drop the unnecessary
VF parameter.

Note that ice_vsi_cfg is not changed as a following change will refactor so
that the VF pointer is assigned during ice_vsi_cfg rather than
ice_vsi_alloc.
