net: chelsio: cxgb3: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  28720	    985	     12	  29717	   7415	net/.../cxgb3/cxgb3_main.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  28848	    857	     12	  29717	   7415	net/.../cxgb3/cxgb3_main.o
