kernel-doc: improve "no structured comments found" error
When using '!Ffile function' in a docbook template, and the function no longer exists, you get a "no structured comments found" error from the kernel-doc processing script. It's useful to know which functions it was looking for, so print them out in this case. Also do the same for '!Pfile doc-section' The same error also happens when using '!Efile' when some exported functions aren't documented (in the same file.) There's a very large number of such functions though, so don't print the message in this case -- right now it would give ~850 messages.
