octeontx2-af: print error message incase of invalid pf mapping
During AF driver initialization, it creates a mapping between pf to
cgx,lmac pair. Whenever there is a physical link change, using this
mapping driver forwards the message to the associated netdev.
This patch prints error message incase of cgx,lmac pair is not
associated with any pf netdev.
