nfp: Replace nfp_pr_et with ethtool_sprintf 

The nfp_pr_et function is nearly identical to ethtool_sprintf except for
the fact that it passes the pointer by value and as a return whereas
ethtool_sprintf passes it as a pointer.

Since they are so close just update nfp to make use of ethtool_sprintf
