iwlagn: move IO functions out of line

This generates a massive reduction in module size:
with debug:
   text    data     bss     dec     hex filename
 670300   13136     420  683856   a6f50 iwlagn.ko (before)
 388347   13136     408  401891   621e3 iwlagn.ko (after)

without debug:
   text    data     bss     dec     hex filename
 528575   13072     420  542067   84573 iwlagn.ko (before)
 294192   13072     408  307672   4b1d8 iwlagn.ko (after)

This also removes all the IO debug functionality since
it can easily be replaced by tracing, and makes the
code unnecessarily complex.

I haven't done any CPU utilisation measurements, but
given that the hotpaths don't use much IO it is not
likely to have a negative impact; in fact, the size
reduction will reduce cache pressure which possibly
improves performance.

Finally, an unused function or two were removed.
