Subject: [PATCH net-next v2 3/4] ice: set vf->num_msix in ice_initialize_vf_entry()

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

Commit fe1c5ca2fe76 ("ice: implement num_msix field per VF") updated the
driver to allow for per-VF MSI-X configuration. The initial defaults were
set in ice_create_vf_entries(). This logic is better placed in
ice_initialize_vf_entry(). Indeed, that function already sets
vf->num_vf_qs, as well as initializes the allow list via calling
ice_vc_set_default_allowlist().

Move this logic into ice_initialize_vf_entry(). This makes the code clear,
and ensures that these VF fields will be initialized properly for both
SR-IOV VFs and the upcoming Scalable IOV VFs.
