[PATCH] wireless: iwlegacy: make const array static to shink object code size Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit

From: Colin Ian King <colin.king@canonical.com>

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)
