    iwlagn: move IO functions out of line · 02a7fa00

    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.
