iwlegacy: make const array static to shink object code size

Browse source 
Don't populate const array ac_to_fifo on the stack in an inlined
function, instead make it static.  Makes the object code smaller
by over 800 bytes:

   text	   data	    bss	    dec	    hex	filename
 159029	  33154	   1216	 193399	  2f377	4965-mac.o

   text	   data	    bss	    dec	    hex	filename
 158122	  33250	   1216	 192588	  2f04c	4965-mac.o

(gcc version 7.2.0 x86_64)
