Subject: [net 7/8] i40e: Update status codes

From: Mitch Williams <mitch.a.williams@...el.com>

Add a few new status code which will be used by the ice driver, and
rename a few to make them more consistent. Error code are mapped to
similar values as in i40e_status.h, so as to be compatible with older
VF drivers not using this status enum.
