ice: remove PF pointer from ice_check_vf_init

The ice_check_vf_init function takes both a PF and a VF pointer. Every
caller looks up the PF pointer from the VF structure. Some callers only
use of the PF pointer is call this function. Move the lookup inside
ice_check_vf_init and drop the unnecessary argument.

Cleanup the callers to drop the now unnecessary local variables. In
particular, replace the local PF pointer with a HW structure pointer in
ice_vc_get_vf_res_msg which simplifies a few accesses to the HW
structure in that function.
