cmd/vet: diagnose using Printf on a function value

Printing a function value is nearly useless outside of debugging, but
can occur by mistake when one forgets to call it. Diagnose this.

I did this myself just the other day and it arose in cl/14031.
Easy to fix and seems worthwhile.

Fixes #12295.
