Subject: [PATCH net-next 08/13] ice: add a function to initialize vf entry

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

Some of the initialization code for Single Root IOV VFs will need to be
reused when we introduce Scalable IOV. Pull this code out into a new
ice_initialize_vf_entry helper function.
