Don't populate the array consumer_rdesc_start on the stack but instead
make it static. Makes the object code smaller by 88 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  59155	   9840	    448	  69443	  10f43	drivers/hid/hid-logitech-hidpp.o

After:
   text	   data	    bss	    dec	    hex	filename
  59003	   9904	    448	  69355	  10eeb	drivers/hid/hid-logitech-hidpp.o

(gcc version 8.3.0, amd64)
