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.
