ixgbevf: add correct exception tracing for XDP

[ Upstream commit faae8142 ]

Add missing exception tracing to XDP when a number of different
errors can occur. The support was only partial. Several errors
where not logged which would confuse the user quite a lot not
knowing where and why the packets disappeared.
