igc: add correct exception tracing for XDP
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.
Fixes: 73f1071c1d29 ("igc: Add support for XDP_TX action")
Fixes: 4ff320361092 ("igc: Add support for XDP_REDIRECT action")
