Alvin Zhang 0c35eecfe8 net/iavf: fix VF to PF command failure handling 
When the command sent by VF to PF fails, iavf may need to run
different code paths according to the specific reason of the
failure (not supported or other reasons).

This patch adds support of identifying PF return error type.

Fixes: 22b123a36d ("net/avf: initialize PMD")
